* Remove QUERY_LIMIT and documenation on same. Change _ALIGN to TYPEALIGNBruce Momjian1999-06-17

* Reset evaluation plan tuple table next free slot counter to 0Vadim B. Mikheev1999-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | after ExecEndNode. It must be done! Or we'll be out of free tuple slots very soon, though slots are freed by ExecEndNode and ready for reusing. We didn't see this problem before because of int nSlots = ExecCountSlotsNode(plan); TupleTable tupleTable = ExecCreateTupleTable(nSlots + 10); /* why add ten? - jolly */ code in InitPlan - i.e. extra 10 slots. Simple select uses 3 slots and so it was possible to re-use evaluation plan 3 additional times and didn't get elog(NOTICE, "Plan requires more slots than are available"); elog(ERROR, "send mail to your local executor guru to fix this"); Changes are obvious and shouldn't be problems with them. Though, I added Assert(epqstate->es_tupleTable->next == 0) before EvalPlanQual():ExecInitNode and we'll notice if something is still wrong. Is it better to change Assert to elog(ERROR) ?

* From: Tatsuo Ishii <t-ishii@sra.co.jp>Marc G. Fournier1999-02-21
| | | | | | Ok. I made patches replacing all of "#if FALSE" or "#if 0" to "#ifdef NOT_USED" for current. I have tested these patches in that the postgres binaries are identical.

* Changed ExecConstraints() and ExecRelCheck() to cache the constraintsJan Wieck1999-02-07
| | | | | | | | | qualification expression trees in the execution state. Prevents from memory exhaustion on INSERT, UPDATE or COPY to tables that have CHECK constraints. Speedup against the variant using freeObject() is more than factor 2. Jan

* First step done,Marc G. Fournier1998-02-21
| | | | | | | | | | | | | | | | | | | below is the patch to have views to override the permission checks for the accessed tables. Now we can do the following: CREATE VIEW db_user AS SELECT usename, usesysid, usecreatedb, usetrace, usecatupd, '**********'::text as passwd, valuntil FROM pg_user; REVOKE ALL ON pg_user FROM public; REVOKE ALL ON db_user FROM public; GRANT SELECT ON db_user TO public;
