flags unique
* Allow configuration files to be specified in a different directory

-* Allow pg_dump to dump sequences using NO_MAXVALUE and NO_MINVALUE
+* -Allow pg_dump to dump sequences using NO_MAXVALUE and NO_MINVALUE
* Allow backend to output result sets in XML
-* Prevent whole-row references from leaking memory, e.g. SELECT COUNT(tab.*)
+* -Prevent whole-row references from leaking memory, e.g. SELECT COUNT(tab.*)
* Have initdb set DateStyle based on locale?

* Allow functions to have a search path specified at creation time
-* Make LENGTH() of CHAR() not count trailing spaces
+* -Make LENGTH() of CHAR() not count trailing spaces
* Allow substring/replace() to get/set bit values
* Add GUC variable to allow output of interval values in ISO8601 format
* Use bitmaps to fetch heap pages in sequential order [performance]
* Use bitmaps to combine existing indexes [performance]
* Allow use of indexes to search for NULLs
-* Allow SELECT * FROM tab WHERE int2col = 4 to use int2col index, int8,
+* -Allow SELECT * FROM tab WHERE int2col = 4 to use int2col index, int8,
float4, numeric/decimal too
* Add FILLFACTOR to btree index creation
* Add concurrency to GIST
(Christopher)
* Dump large object comments in custom dump format
* Add optional textual message to NOTIFY
-* Allow more ISOLATION LEVELS to be accepted, but issue a warning for them
+* -Allow more ISOLATION LEVELS to be accepted
* Allow CREATE TABLE foo (f1 INT CHECK (f1 > 0) CHECK (f1 < 10)) to work
by searching for non-conflicting constraint names, and prefix with table name
* Use more reliable method for CREATE DATABASE to get a consistent copy of db
* -Have psql \dn show only visible temp schemas using current_schemas()
* -Have psql '\i ~/<tab><tab>' actually load files it displays from home dir
* Ignore temporary tables from other session when processing inheritance
-* Add GUC setting to make created tables default to WITHOUT OIDS
+* -Add GUC setting to make created tables default to WITHOUT OIDS
* Have pg_ctl look at PGHOST in case it is a socket directory
* Allow column-level privileges
* Add a session mode to warn about non-standard SQL usage

* -Allow pg_dump to dump CREATE CONVERSION (Christopher)
-* Allow fastpast to pass values in portable format
* Allow libpq to return information about prepared queries
* -Make pg_restore continue after errors, so it acts more like pg_dump scripts
* Have psql show more information about sequences
* Allow pg_dumpall to use non-text output formats
* Have pg_dump use multi-statement transactions for INSERT dumps
-* Move psql backslash database information into the backend, use nmumonic
+* Move psql backslash database information into the backend, use nmeumonic
commands? [psql]
-* JDBC
- o Comprehensive test suite. This may be available already.
- o JDBC-standard BLOB support
- o Error Codes (pending backend implementation)
- o Support both 'make' and 'ant'
- o Fix LargeObject API to handle OIDs as unsigned ints
- o Use cursors implicitly to avoid large results (see setCursorName())
- o Add LISTEN/NOTIFY support to the JDBC driver (Barry)
-
* ECPG
o Docs
o Implement set descriptor, using descriptor
* Flush cached query plans when their underlying catalog data changes
* -Use dependency information to dump data in proper order
-* Have pg_dump -c clear the database using dependency information
+* -Have pg_dump -c clear the database using dependency information
Exotic Features
* Shared catalog cache, reduce lseek()'s by caching table size in shared area
* Add free-behind capability for large sequential scans [fadvise]
* Consider use of open/fcntl(O_DIRECT) to minimize OS caching
-* Cache last known per-tuple offsets to speed long tuple access
-* Automatically place fixed-width, NOT NULL columns first in a table
+* Cache last known per-tuple offsets to speed long tuple access, adjusting
+ for NULLs and TOAST values
* Use a fixed row count and a +/- count with MVCC visibility rules
to allow fast COUNT(*) queries with no WHERE clause(?) [count]
* Create improved PostgreSQL introductory documentation for the PHP
manuals
* Add optional CRC checksum to heap and index pages
-* Change representation of whole-tuple parameters to functions
+* -Change representation of whole-tuple parameters to functions
+* Support composite types as table columns
* Clarify use of 'application' and 'command' tags in SGML docs
* Better document ability to build only certain interfaces (Marc)
* Remove or relicense modules that are not under the BSD license, if possible
* -Change CVS ID to PostgreSQL
* -Exit postmaster if postgresql.conf can not be opened
* Rename /scripts directory because they are all C programs now
-* Allow the regression tests to start postmaster with -i so the tests
- can be run on systems that don't support unix-domain sockets
* Allow creation of a libpq-only tarball
* Promote debug_query_string into a server-side function current_query()
* Allow the identifier length to be increased via a configure option
