First stage of reclaiming memory in executor by resetting short-term memory contexts. Currently, only leaks in expressions executed as quals or projections are handled. Clean up some old dead cruft in executor while at it --- unused fields in state nodes, that sort of thing.

Use a private memory context to store rule information in each relcache entry that has rules. This allows us to release the rule parsetrees on relcache flush without needing a working freeObject() routine. Formerly, the rule trees were leaked permanently at relcache flush. Also, clean up handling of rule creation and deletion --- there was not sufficient locking of the relation being modified, and there was no reliable notification of other backends that a relcache reload was needed. Also, clean up relcache.c code so that scans of system tables needed to load a relcache entry are done in the caller's memory context, not in CacheMemoryContext. This prevents any un-pfreed memory from those scans from becoming a permanent memory leak.

Commit of a *MAJOR* patch from Dan McGuirk <djm@indirect.com> Changes: * Unique index capability works using the syntax 'create unique index'. * Duplicate OID's in the system tables are removed. I put little scripts called 'duplicate_oids' and 'find_oid' in include/catalog that help to find and remove duplicate OID's. I also moved 'unused_oids' from backend/catalog to include/catalog, since it has to be in the same directory as the include files in order to work. * The backend tries converting the name of a function or aggregate to all lowercase if the original name given doesn't work (mostly for compatibility with ODBC). * You can 'SELECT NULL' to your heart's content. * I put my _bt_updateitem fix in instead, which uses _bt_insertonpg so that even if the new key is so big that the page has to be split, everything still works. * All literal references to system catalog OID's have been replaced with references to define'd constants from the catalog header files. * I added a couple of node copy functions. I think this was a preliminary attempt to get rules to work.

bool islossy,
The following patch finishes primary key support. Previously, when a field was labelled as a primary key, the system automatically created a unique index on the field. This patch extends it so that the index has the indisprimary field set. You can pull a list of primary keys with the followiing select. SELECT pg_class.relname, pg_attribute.attname FROM pg_class, pg_attribute, pg_index WHERE pg_class.oid = pg_attribute.attrelid AND pg_class.oid = pg_index.indrelid AND pg_index.indkey[0] = pg_attribute.attnum AND pg_index.indisunique = 't'; There is nothing in this patch that modifies the template database to set the indisprimary attribute for system tables. Should they be changed or should we only be concerned with user tables? D'Arcy

bool unique,
Make toast-table creation and deletion work somewhat reliably. Don't go through pg_exec_query_dest(), but directly to the execution routines. Also, extend parameter lists so that there's no need to change the global setting of allowSystemTableMods, a hack that was certain to cause trouble in the event of any error.

Get rid of IndexIsUniqueNoCache() kluge by the simple expedient of passing the index-is-unique flag to index build routines (duh! ... why wasn't it done this way to begin with?).
