-* -Allow ORDER BY...LIMIT in INSERT INTO ... SELECT (Tom)
* Add SHOW command to display locks
CLIENTS

+ * Allow specification of column names
+ * Allow dump/load of CSV format
* fix array handling for ECPG
* -add pg_dump option to dump type names as standard ANSI types
* -make pg_dump dump in oid order, so dependencies are resolved (Philip)
* Incremental backups
* Allow SQL92 schemas
-MISC
+MISCELLANEOUS
* Increase identifier length(NAMEDATALEN) if small performance hit
* Create a background process for each database that runs while
* Missing optimizer selectivities for date, r-tree, etc. [optimizer]
* Overhaul bufmgr/lockmgr/transaction manager
* -redesign UNION structures to have separarate target lists
-* -Allow multi-level query trees for INSERT INTO ... SELECT

-* -Redesign ANALYZE in VACUUM so it can be run separately without locks
-* Make ANALYZE a separate command
* Gather more accurate dispersion statistics using indexes
* Improve statistics storage in pg_class [performance]
-* Improve VACUUM speed with indexes [vacuum]
-* Reduce VACUUM lock time by moving tuples with read lock, then write
