-Tue Mar 06 12:05:00 GMT 2001 peter@retep.org.uk
- - Removed org.postgresql.xa.Test from the JDBC EE driver as it's an old
- test class and prevented it from compiling.
-
-Fri Mar 02 10:00:00 GMT 2001 peter@retep.org.uk
- - Fixed build.xml so that PGclob is not built in the JDBC1.2 driver
-
-
-Fri Feb 17 18:25:00 GMT 2001 peter@retep.org.uk
- - Removed the last deprecation warnings from the Java2 driver. Now only
- the old examples give deprecation warnings.
- - Added a new class into core that (JDK1.3+) ensures all connections are
- closed when the VM terminates.
-
-Fri Feb 17 15:11:00 GMT 2001 peter@retep.org.uk
- - Reduced the object overhead in PreparedStatement by reusing the same
- StringBuffer object throughout. Similarly SimpleDateStamp's are alse
- reused in a thread save manner.
- - Implemented in PreparedStatement: setNull(), setDate/Time/Timestamp
- using Calendar, setBlob(), setCharacterStream()
- - Clob's are now implemented in ResultSet & PreparedStatement!
- - Implemented a lot of DatabaseMetaData & ResultSetMetaData methods.
- We have about 18 unimplemented methods left in JDBC2 at the current
- time.
-
-Web Feb 14 17:29:00 GMT 2001 peter@retep.org.uk
- - Fixed bug in LargeObject & BlobOutputStream where the stream's output
- was not flushed when either the stream or the blob were closed.
- - Fixed PreparedStatement.setBinaryStream() where it ignored the length
-
-Tue Feb 13 16:33:00 GMT 2001 peter@retep.org.uk
- - More TestCases implemented. Refined the test suite api's.
- - Removed need for SimpleDateFormat in ResultSet.getDate() improving
- performance.
- - Rewrote ResultSet.getTime() so that it uses JDK api's better.
-
-Tue Feb 13 10:25:00 GMT 2001 peter@retep.org.uk
- - Added MiscTest to hold reported problems from users.
- - Fixed PGMoney.
- - JBuilder4/JDBCExplorer now works with Money fields. Patched Field &
- ResultSet (lots of methods) for this one. Also changed cash/money to
- return type DOUBLE not DECIMAL. This broke JBuilder as zero scale
- BigDecimal's can't have decimal places!
- - When a Statement is reused, the previous ResultSet is now closed.
- - Removed deprecated call in ResultSet.getTime()
-
-Thu Feb 08 18:53:00 GMT 2001 peter@retep.org.uk
- - Changed a couple of settings in DatabaseMetaData where 7.1 now
- supports those features
- - Implemented the DatabaseMetaData TestCase.
-
-Wed Feb 07 18:06:00 GMT 2001 peter@retep.org.uk
- - Added comment to Connection.isClosed() explaining why we deviate from
- the JDBC2 specification.
- - Fixed bug where the Isolation Level is lost while in autocommit mode.
- - Fixed bug where several calls to getTransactionIsolationLevel()
- returned the first call's result.
-
-Tue Feb 06 19:00:00 GMT 2001 peter@retep.org.uk
- - Completed first two TestCase's for the test suite. JUnit is now
- recognised by ant.
-
-Wed Jan 31 08:46:00 GMT 2001 peter@retep.org.uk
- - Some minor additions to Statement to make our own extensions more
- portable.
- - Statement.close() will now call ResultSet.close() rather than just
- dissasociating with it.
-
-Tue Jan 30 22:24:00 GMT 2001 peter@retep.org.uk
- - Fixed bug where Statement.setMaxRows() was a global setting. Now
- limited to just itself.
- - Changed LargeObject.read(byte[],int,int) to return the actual number
- of bytes read (used to be void).
- - LargeObject now supports InputStream's!
- - PreparedStatement.setBinaryStream() now works!
- - ResultSet.getBinaryStream() now returns an InputStream that doesn't
- copy the blob into memory first!
- - Connection.isClosed() now tests to see if the connection is still alive
- rather than if it thinks it's alive.
-Thu Jan 25 09:11:00 GMT 2001 peter@retep.org.uk
- - Added an alternative constructor to PGSQLException so that debugging
- some more osteric bugs is easier. If only 1 arg is supplied and it's
- of type Exception, then that Exception's stacktrace is now included.
-
-Wed Jan 24 09:18:00 GMT 2001 peter@retep.org.uk
- - Removed the 8k limit by setting it to 64k
-
-Fri Jan 19 08:47:00 GMT 2001 peter@retep.org.uk
- - Applied patch submitted by John Schutz <schutz@austin.rr.com> that
- fixed a bug with ANT's SQL functions (not needed for building but nice
- to have fixed).
-
-Thu Jan 18 17:30:00 GMT 2001 peter@retep.org.uk
- - Added new error message into errors.properties "postgresql.notsensitive"
- This is used by jdbc2.ResultSet when a method is called that should
- fetch the current value of a row from the database refreshRow() for
- example.
- - These methods no longer throw the not implemented but the new noupdate
- error. This is in preparation for the Updateable ResultSet support
- which will overide these methods by extending the existing class to
- implement that functionality, but needed to show something other than
- notimplemented:
- moveToCurrentRow()
- moveToInsertRow()
- rowDeleted()
- rowInserted()
- all update*() methods, except those that took the column as a String
- as they were already implemented to convert the String to an int.
- - getFetchDirection() and setFetchDirection() now throws
- "postgresql.notimp" as we only support one direction.
- The CursorResultSet will overide this when its implemented.
- - Created a new class under jdbc2 UpdateableResultSet which extends
- ResultSet and overides the relevent update methods.
- This allows us to implement them easily at a later date.
- - In jdbc2.Connection, the following methods are now implemented:
- createStatement(type,concurrency);
- getTypeMap();
- setTypeMap(Map);
- - The JDBC2 type mapping scheme almost complete, just needs SQLInput &
- SQLOutput to be implemented.
- - Removed some Statement methods that somehow appeared in Connection.
- - In jdbc2.Statement()
- getResultSetConcurrency()
- getResultSetType()
- setResultSetConcurrency()
- setResultSetType()
- - Finally removed the old 6.5.x driver.
-
-Thu Jan 18 12:24:00 GMT 2001 peter@retep.org.uk
- - These methods in org.postgresql.jdbc2.ResultSet are now implemented:
- getBigDecimal(int) ie: without a scale (why did this get missed?)
- getBlob(int)
- getCharacterStream(int)
- getConcurrency()
- getDate(int,Calendar)
- getFetchDirection()
- getFetchSize()
- getTime(int,Calendar)
- getTimestamp(int,Calendar)
- getType()
- NB: Where int represents the column name, the associated version
- taking a String were already implemented by calling the int
- version.
- - These methods no longer throw the not implemented but the new noupdate
- error. This is in preparation for the Updateable ResultSet support
- which will overide these methods by extending the existing class to
- implement that functionality, but needed to show something other than
- notimplemented:
- cancelRowUpdates()
- deleteRow()
- - Added new error message into errors.properties "postgresql.noupdate"
- This is used by jdbc2.ResultSet when an update method is called and
- the ResultSet is not updateable. A new method notUpdateable() has been
- added to that class to throw this exception, keeping the binary size
- down.
- - Added new error message into errors.properties "postgresql.psqlnotimp"
- This is used instead of unimplemented when it's a feature in the
- backend that is preventing this method from being implemented.
- - Removed getKeysetSize() as its not part of the ResultSet API
-
-Thu Jan 18 09:46:00 GMT 2001 peter@retep.org.uk
- - Applied modified patch from Richard Bullington-McGuire
- <rbulling@microstate.com>. I had to modify it as some of the code
- patched now exists in different classes, and some of it actually
- patched obsolete code.
-
-Wed Jan 17 10:19:00 GMT 2001 peter@retep.org.uk
- - Updated Implementation to include both ANT & JBuilder
- - Updated README to reflect the changes since 7.0
- - Created jdbc.jpr file which allows JBuilder to be used to edit the
- source. JBuilder _CAN_NOT_ be used to compile. You must use ANT for
- that. It's only to allow JBuilders syntax checking to improve the
- drivers source. Refer to Implementation for more details
-
-Wed Dec 20 16:19:00 GMT 2000 peter@retep.org.uk
- - Finished build.xml and updated Driver.java.in and buildDriver to
- match how Makefile and ANT operate.
-
-Tue Dec 19 17:30:00 GMT 2000 peter@retep.org.uk
- - Finally created ant build.xml file
-
-Mon Nov 20 08:12:00 GMT 2000 peter@retep.org.uk
- - Encoding patch to Connection by wrobell@posexperts.com.pl
-
-Tue Oct 17 15:35:00 BST 2000 petermount@maidstone.gov.uk
- - Changed getTimestamp() again. This time Michael Stephenson's
- <mstephenson@tirin.openworld.co.uk> solution looked far better
- than the original solution put in June.
-
-Tue Oct 10 13:12:00 BST 2000 peter@retep.org.uk
- - DatabaseMetaData.supportsAlterTableWithDropColumn() as psql doesn't
- support dropping of individual columns
- - Merged in some last patches. Only 1 left, which may not be compatible
- with jdbc1
- - Merged in my old retepsql project. Makefile now includes it.
-
-Mon Oct 02 12:30:00 BST 2000 peter@retep.org.uk
- - Merged in byte[] array allocation changes submitted by Gunnar R|nning
- <gunnar@candleweb.no>
-
-Mon Sep 25 14:22:00 BST 2000 peter@retep.org.uk
- - Removed the DriverClass kludge. Now the org.postgresql.Driver class
- is compiled from a template file, and now has both the connection
- class (ie jdbc1/jdbc2) and the current version's from Makefile.global
-
-Thu Jul 20 16:30:00 BST 2000 petermount@it.maidstone.gov.uk
- - Fixed DatabaseMetaData.getTableTypes()
-
-Tue Jun 06 12:00:00 BST 2000 petermount@it.maidstone.gov.uk
- - Added org/postgresql/DriverClass.java to the list of files removed
- by make clean (it's dynamically built)
- - Fixed Statement, so that the update count is valid when an SQL
- DELETE operation is done.
- - While fixing the update count, made it easier to get the OID of
- the last insert as well. Example is in example/basic.java
-
-Tue Jun 06 08:37:00 BST 2000 petermount@it.maidstone.gov.uk
- - Removed a hardwired 8K limit on query strings
- - Added some missing org.'s in Connection that prevented
- the use of the geometric types.
-
-Thu Jun 01 07:26:00 BST 2000 petermount@it.maidstone.gov.uk
- - Removed timezone in getTimestamp() methods in ResultSet.
-
-Mon May 15 22:30:00 BST 2000 peter@retep.org.uk
- - Fixed the message Makefile produces after compiling. It still said
- about the old Driver class, not the new package. Spotted by
- Joseph Shraibman <jks@p1.selectacast.net>
-
-Thu May 04 11:38:00 BST 2000 petermount@it.maidstone.gov.uk
- - Corrected incorrect date in CHANGELOG
- - Fixed the ImageViewer example
-
-Wed May 03 16:47:00 BST 2000 petermount@it.maidstone.gov.uk
- - Fixed the Makefile so that postgresql.jar is built everytime
- the jdbc1 or jdbc2 rules are called.
- - Fixed the threadsafe example. It had problems with autocommit
-
-Wed May 03 14:32:00 BST 2000 petermount@it.maidstone.gov.uk
- - Rewrote the README file (the old one was 18 months old!)
- - Added @deprecated tags to org.postgresql.jdbc2.ResultSet
- to clear some warnings issued during compilation.
-
-Wed Apr 12 22:14:00 BST 2000 peter@retep.org.uk

-Tue Feb 1 21:40:00 GMT 2000 peter@retep.org.uk
- - Finally imported the contributed javax extensions by Assaf Arkin
- arkin@exoffice.com
-
-Mon Jan 24 21:00:00 GMT 2000 peter@retep.org.uk
- - Finally introduced the 7.0 additions to the core CVS repository.
- - All source files are now under the org.postgresql package (previously
- they were under postgresql). The package lines now changed
- accordingly.
- - The Makefile was rewritten so it should now work on machines that
- can't handle the $( ) syntax.
- - Dutch translation by Arnout Kuiper (ajkuiper@wxs.nl)
-
-Mon Sep 13 23:56:00 BST 1999 peter@retep.org.uk
- - PG_Stream.SendChar() optimised, increased default buffer size of
- output stream to 8k, and introduced an 8k buffer on the input stream
- Sverre H Huseby <sverrehu@online.no>
- - Added a finalize() method to Connection class in both drivers so that
- the connection to the backend is really closed.
- - Due to many JVM's not returning a meaningful value for java.version
- the decision for building the JDBC1.2 or JDBC2 driver is now a
- compile time option.
- - Replaced $$(cmd...) with `cmd...` in the Makefile. This should allow
- the driver to compile when using shells other than Bash.
-
-Thu Sep 9 01:18:39 MEST 1999 jens@jens.de
- - fixed bug in handling of DECIMAL type
-
-Wed Aug 4 00:25:18 CEST 1999 jens@jens.de
- - updated ResultSetMetaData.getColumnDisplaySize() to return
- the actual display size
- - updated driver to use postgresql FE/BE-protocol version 2

- - Fixed typo in postgresql.Driver that prevented compilation
- - Implemented getTimestamp() fix submitted by Philipp Matthias Hahn
- <pmhahn@titan.lahn.de>
- - Cleaned up some comments in Connection
-
-Wed Jun 23 06:50:00 BST 1999
- - Fixed error in errors.properties where the arguments are 0 based not
- 1 based
- - Fixed bug in postgresql.Driver where exception is thrown, then
- intercepted rather than being passed to the calling application.
- - Removed the file postgresql/CallableStatement, as it's not used and
- really exists in the jdbc1 & jdbc2 sub packages only.
-
-Wed May 19 00:20:00 BST 1999
- - Internationalisation now done. Surprising that there's 68 error
- messages in the driver ;-)
-
-Tue May 18 07:00:00 BST 1999
- - Set the ImageViewer application to use transactions
-
-Tue May 18 00:00:00 BST 1999
- - Just after committing, I realised why internationalisation isn't
- working. This is now fixed (in the Makefile).
-
-Mon May 17 23:40:00 BST 1999
- - PG_Stream.close() now attempts to send the close connection message
- to the backend before closing the streams
- - Added batch support in the JDBC2, supplied by Yutaka Tanida
- <yutaka@marin.or.jp>
- - Removed the old datestyle code. Now the driver uses only ISO.
- - Removed some files in the postgresql directory still in CVS that were
- moved since 6.4.x (DatabaseMetaData.java PreparedStatement.java
- ResultSetMetaData.java Statement.java)
- - Internationalisation of the error messages is partially implemented,
- however it's not enabled as it only works when the jar file is
- _not_ used, and work needs to be done.
-
-Sun Apr 11 17:00:00 BST 1999
- - getUpdateCount() now returns the actual update count (before it
- simply returned 1 for everything).
- - added some updates to example.basic so it would test the new update
- count code.
- - corrected typo in a comment in Statement.java
-
-Mon Jan 25 19:45:00 GMT 1999
- - created subfolders example/corba and example/corba/idl to hold the
- new example showing how to hook CORBA and PostgreSQL via JDBC
- - implemented some JDBC2 methods curtesy of Joachim.Gabler@t-online.de
-
-Sat Jan 23 10:30:00 GMT 1999
- - Changed imports in postgresql.jdbc1.ResultSetMetaData as for some
- reason it didn't want to compile under jdk1.1.6
-
-Tue Dec 29 15:45:00 GMT 1998
- - Refreshed the README (which was way out of date)
-
-Tue Dec 29 15:45:00 GMT 1998
- - Finished adding the additional methods into the JDBC2 driver.
- - Had to add some explicit package references for the JDK1.2 Javac to
- cope with the driver
-
-Tue Dec 29 12:40:00 GMT 1998
- - Fixed package imports and some references to java.sql.ResultSet in
- various files. Compiled and tested the JDBC1 driver.
-
-Mon Dec 28 19:01:37 GMT 1998
- - created a new package postgresql.jdbc2 which will contain the JDBC 2
- specific classes. A similar new package (postgresql.jdbc1) has been
- created to hold the JDBC 1 specific classes.
- - modified Makefile to allow compilation of the JDBC 1 & 2 drivers,
- with the possibility of building a dual-spec driver.
- - changed the version number in postgresql.Driver to 6.5
- - modified postgresql.Driver class to initiate the correct driver when
- used under a 1.1 or 1.2+ JVM.
- - postgresql.Connection and postgresql.jdbc2.Connection now extends the
- new class postgresql.ConnectionStub, which allows us to dynamically
- open the JDBC1 or JDBC2 drivers.
- - enabled compilation of the driver under Win32 when using the Make
- from the CygWin package (Cygnus B20.1 was used).
- - To make future development easier (now we have 2 specifications to
- work with) the following classes have moved from the postgresql to
- the postgresql.jdbc1 package:
- CallableStatement Connection
- DatabaseMetaData PreparedStatement
- ResultSet ResultSetMetaData
- Statement
- Some of these classes have common code that is not dependent on
- either JDBC specification. These common code are still in the
- postgresql package.
- Ie: postgresql.jdbc1.Connection extends postgresql.Connection
- and postgresql.jdbc2.Connection extends postgresql.Connection
-
-Web Oct 7 22:00:00 BST 1998
- - removed syncronised from Connection.ExecSQL(). See next entry.
- - added new syncronised locking in the Connection.ExecSQL() and
- FastPath.fastpath() methods. They now lock against the PG_Steam
- object for the connection, which now provides full Thread Safety.
- - Reposted ChangeLog as it's missing from CVS.
-
-Modifications done since 6.3.2 was released and Sun Aug 30 11:33:06 BST 1998
-
- - Fixed PreparedStatement.setObject as it didn't handle shorts
- - ResultSet.getDate() now handles null dates (returns null ratrher
- than a NullPointerException)
- - ResultSetMetaData.getPrecision() new returns 0 for VARCHAR
- - Field now caches the typename->oid in a Hashtable to speed things
- up. It removes the need for some unnecessary queries to the backend.
- - PreparedStatement.toString() now returns the SQL statement that it
- will send to the backend. Before it did nothing.
- - DatabaseMetaData.getTypeInfo() now does something.
- - Connection now throws an exception if either of the user or password
- properties are missing, as they are required for JDBC to work.
- This occasionally occurs when the client uses the properties version
- of getConnection(), and is a common question on the email lists.
-
-Sun Aug 30 11:33:06 BST 1998
-
- - Created ChangeLog file, and entered stuff done since 6.3.2 and today
- - Change version number to 6.4 in Driver.java
- - Added fix to DatabaseMetaData.getTables() submitted by
- Stefan Andreasen <stefan@linux.kapow.dk>
- - Added fix to DatabaseMetaData.getColumns() to handle patterns
- submitted by Stefan Andreasen <stefan@linux.kapow.dk>
- - Set TcpNoDelay on the connection, as this gives us a 10x speed
- improvement on FreeBSD (caused by a bug in their TCP Stack). They
- should fix the bug before 6.4 is released, but will keep this
- in here unless it causes more problems.
- Submitted by Jason Venner <jason@idiom.com>
- - Removed a duplicate definition of fieldCache
- - Added a more meaningful message when the connection is refused. It
- now says:
- Connection refused. Check that the hostname and port is
- correct, and that the postmaster is running with the -i flag,
- which enables TCP/IP networking.
- - Removed kludge in PreparedStatement.setDate() that acted as a
- temporary fix to a bug in SimpleDateFormat, as it broke date
- handling in JDK 1.1.6.
- - Modified PG_Stream and Connection, so that outbound data is now
- buffered. This should give us a speed improvement, and reduce the
- ammount of network packets generated.
- - Removed duplicate code and optimised PG_Stream.
- - PG_Stream now returns a more meaningful message when the connection
- is broken by the backend. It now returns:
- The backend has broken the connection. Possibly the action you
- have attempted has caused it to close.
- - Removed obsolete code from Connection.
- - The error message returned when the authentication scheme is unknown
- has been extended. It now reads:
- Authentication type ### not supported. Check that you have
- configured the pg_hba.conf file to include the client's IP
- address or Subnet, and is using a supported authentication
- scheme.
- - Connection.getMetaData() now caches the instance returned, so
- multiple calls will return the same instance.
- - Created a test application that tests the DatabaseMetaData and
- ResultSetMetaData classes.
- - Replaced getString(#).getBytes() with getBytes(#) which should speed
- things up, and reduce memory useage.
- - Optimised DatabaseMetaData.getProcedures(), and implemented patterns
- - Fixed NullPointerExceptions thrown when a field is null (Internal
- to the driver, not caused by results from the backend.
- DatabaseMetaData.getProcedures() is an example of a method that
- causes this):
- - ResultSetMetaData.getColumnName() now returns field# where
- # is the column name.
- - ResultSet.getObject() fixed
- - Fixed bug in psql example that was affected by null fields
- - DatabaseMetaData.getTables()
- - DatabaseMetaData.getPrimaryKeys() ran a query with an ambiguous field
- fixed.
- - getTypeInfo() optimised to increase speed and reduce memory useage
- - ResultSetMetaData.isCurrency() optimised and is now smaller.
- - Removed unnecessary code fromResultSetMetaData.getCatalogName()
- and getSchemaName().
- - Created new class postgresql.util.PGmoney to map the money type
- - Created new class postgresql.geometric.PGline to map the line type

+++ /dev/null
-This short document is provided to help programmers through the internals of
-the PostgreSQL JDBC driver.
-
-Last update: January 17 2001 peter@retep.org.uk
-
-build.xml
----------
-
-As of 7.1, we now use the ANT build tool to build the driver. ANT is part of
-the Apache/Jakarta project, and provides far superior build capabilities. You
-can find ANT from http://jakarta.apache.org/ant/index.html and being pure java
-it will run on any java platform.
-
-So far I've tested it under JDK1.2.x & JDK1.3 (both Linux & NT) but not yet with
-JDK1.1.8. Because of the latter the Makefile still works for now, but should be
-gone for 7.2.
-
-Anyhow, to build, simply type ant and the .jar file will be created and put into
-the jars directory.
-
-Tip: If you run ant from the sources root directory (ie: where the configure
-script is located) you will find another build.xml file. It is advised to run
-ant from that directory as it will then compile some auxilary Java/JDBC
-utilities that are located under the /contrib/retep directory.
-
-Makefile
---------
-
-Prior to 7.1, all compilation must be done by using Make. This is because there
-are three versions of the driver, one for JDBC1 (for JDK 1.1.x) and the others
-for JDBC2 (for JDK 1.2 or later, one standard and one enterprise).
-
-As of 7.1, ANT is the build tool of choice. Just compare Makefile and build.xml
-to see why! Make just isn't suited to Java.
-
-Building with just the JDK
---------------------------
-
-This is not advised, simply because you have to make sure you include the
-correct classes, and the fact that org.postgresql.Driver is built on the fly.
-Also, javac won't pick up all the classes because some (org.postgresql.geometric
-for example) are loaded dynamically.
-
-org/postgresql/Driver.java.in
------------------------------
-
-Because there are three versions of the driver, the org.postgresql.Driver class
-is built dynamically. To build correctly ANT copies the Driver.java.in file to
-Driver.java replacing certain values according to the required driver.
-
-The replaced values are of the format %VALUE%, ie: %MAJORVERSION% is replaced
-with 7 in the 7.1 version of the driver.
-
-postgresql.jar
---------------
-
-This jar file is produced by ANT, and contains the driver for your JDK platform.
-
-If you downloaded a precompiled binary from the web, you may find that the
-jar file will be named differently. These are identical to this file but are
-named according to the backend and jdk versions.
-
-The naming convention is of the form: jdbc-#.#-#.##.jar
-
-ie: for 7.1
- jdbc-7.1-1.1.jar JDBC Driver for JDK1.1.8
- jdbc-7.1-1.2.jar JDBC Driver for JDK1.2 & JDK1.3
- jdbc-7.1-1.2ent.jar JDBC Driver for JDK1.2 & JDK1.3 Enterprise Editions
-
-If in the future there are any 1.3 specific classes then there will be two new
-jar files.
-
-Note: All the precompiled binaries are built under Linux.
-
-jdbc.jpx
---------
-
-This is a JBuilder4 project file. It's here to allow JBuilder to be used to
-develop the driver. Mainly for it's Editor's features like syntax checking and
-auto-completion etc.
-
-IMPORTANT: You CAN NOT build the driver from within JBuilder. You must use ANT.
- This is because of the three versions of the JDK. If you try to use
- JBuilder, it will try to build everything, and it will just not work.
-
-Importing packages
-------------------
-
-In user code, you may have to import one or more packages, if and only if you
-are using the non jdbc extensions (like FastPath, or LargeObject).
-
-DO NOT import the postgresql, postgresql.jdbc1 or postgresql.jdbc2 packages!
-
-Internally, some classes will import the packages when there is a link between
-them and the other packages. However, the above rule still applies. It's there
-because Javac becomes confused between the different places that similar class
-names are present.
-
-However, there are places where they need to refer to classes in the postgresql
-package. In this case, import the individual classes, and not the entire
-package.
-
-ie: import postgresql.Field
-
- NOT import postgresql.*
-
-Package Layout
---------------
-
-The driver is split into several packages:

-
-Package org.postgresql
-------------------
-
-This package holds the core classes.
-
-Driver registers the driver when it's loaded, and determines which
- Connection class (in jdbc1 or jdbc2 packages) to use when
- connecting to a database.
-
-Field Used internally to represent a Field
-PG_Stream Used internally to manage the network stream.
-PostgresqlDataSource
- Exists in the Java2 Enterprise edition driver only and is the
- enterprise equivalent to Driver
-
- These classes contains common code that is not dependent to the
- two JDBC specifications.
-
-Connection Common code used in Connections, mainly Network Protocol stuff.
-ResultSet Common code used in ResultSet's
-
-Package org.postgresql.core
------------------------
-
-New in 7.1, this is where core classes (common to all versions) will exist. Any
-new class that would have gone into org.postgresql must go in here instead.
-
-BytePoolDim1 Handles a pool of byte[] arrays.
-BytePoolDim2 Handles a pool of byte[][] arrays
-MemoryPool Interface for managing MemoryPools. Not used (yet).
-ObjectPool Interface for an Object Pool
-SimpleObjectPool Class that implements ObjectPool and used by BytePoolDim#
-Encoding Character encoding logic, mainly for Connection and PG_Stream.

-LargeObjectManager Handles the opening and deleting of LargeObjects
-
-Package org.postgresql.util
------------------------
-
-PGmoney Maps to postgresql type money
-PGobject Used to represent postgresql types that have no Java equivalent
