+* -Allow LIKE indexing optimization for non-ASCII locales using special index
* Use index to restrict rows returned by multi-key index when used with
non-consecutive keys or OR clauses, so fewer heap accesses

+ o Add capability to create and call PROCEDURES
Clients

and use that as part of pg_dump along with psql
-

* JDBC
Optimizer / Executor
====================
-* Improve Subplan list handling
+* -Improve Subplan list handling
* -Allow Subplans to use efficient joins(hash, merge) with upper variable
* -Add hash for evaluating GROUP BY aggregates (Tom)
* -Allow merge and hash joins on expressions not just simple variables (Tom)
* Acquire lock on a relation before building a relcache entry for it
* Research interaction of setitimer() and sleep() used by statement_timeout
* Add checks for fclose() failure
