+ - 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.

+
+ - 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
