Tom Lane	badce86a2c	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.	26 years ago
Bruce Momjian	946e80c435	Final #include cleanup.	26 years ago
Bruce Momjian	5c25d60244	Add: ... * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.	26 years ago
Tom Lane	6d1efd76fb	Fix handling of NULL constraint conditions: per SQL92 spec, a NULL result ... from a constraint condition does not violate the constraint (cf. discussion on pghackers 12/9/99). Implemented by adding a parameter to ExecQual, specifying whether to return TRUE or FALSE when the qual result is really NULL in three-valued boolean logic. Currently, ExecRelCheck is the only caller that asks for TRUE, but if we find any other places that have the wrong response to NULL, it'll be easy to fix them.	26 years ago
Bruce Momjian	fc955b14ea	Add system indexes to match all caches. ... Make all system indexes unique. Make all cache loads use system indexes. Rename *rel to *relid in inheritance tables. Rename cache names to be clearer.	26 years ago

Tom Lane	e812458b27	Several changes here, not very related but touching some of the same files. ... * Buffer refcount cleanup (per my "progress report" to pghackers, 9/22). * Add links to backend PROC structs to sinval's array of per-backend info, and use these links for routines that need to check the state of all backends (rather than the slow, complicated search of the ShmemIndex hashtable that was used before). Add databaseOID to PROC structs. * Use this to implement an interlock that prevents DESTROY DATABASE of a database containing running backends. (It's a little tricky to prevent a concurrently-starting backend from getting in there, since the new backend is not able to lock anything at the time it tries to look up its database in pg_database. My solution is to recheck that the DB is OK at the end of InitPostgres. It may not be a 100% solution, but it's a lot better than no interlock at all...) * In ALTER TABLE RENAME, flush buffers for the relation before doing the rename of the physical files, to ensure we don't get failures later from mdblindwrt(). * Update TRUNCATE patch so that it actually compiles against current sources :-(. You should do "make clean all" after pulling these changes.	27 years ago

Bruce Momjian	460b20a43f	1) Queries using the having clause on base tables should work well ... now. Here some tested features, (examples included in the patch): 1.1) Subselects in the having clause 1.2) Double nested subselects 1.3) Subselects used in the where clause and in the having clause simultaneously 1.4) Union Selects using having 1.5) Indexes on the base relations are used correctly 1.6) Unallowed Queries are prevented (e.g. qualifications in the having clause that belong to the where clause) 1.7) Insert into as select 2) Queries using the having clause on view relations also work but there are some restrictions: 2.1) Create View as Select ... Having ...; using base tables in the select 2.1.1) The Query rewrite system: 2.1.2) Why are only simple queries allowed against a view from 2.1) ? 2.2) Select ... from testview1, testview2, ... having...; 3) Bug in ExecMergeJoin ??
