* First cut at full support for OUTER JOINs. There are still a few looseTom Lane2000-09-121-36/+37
| | | | | ends to clean up (see my message of same date to pghackers), but mostly it works. INITDB REQUIRED!
* First stage of reclaiming memory in executor by resetting short-termTom Lane2000-07-121-23/+10
| | | | | | 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.
* Ye-old pgindent run. Same 4-space tabs.Bruce Momjian2000-04-121-9/+11

* Redesign DISTINCT ON as discussed in pgsql-sql 1/25/00: syntax is nowTom Lane2000-01-271-2/+2
| | | | | | | | | | | | | SELECT DISTINCT ON (expr [, expr ...]) targetlist ... and there is a check to make sure that the user didn't specify an ORDER BY that's incompatible with the DISTINCT operation. Reimplement nodeUnique and nodeGroup to use the proper datatype-specific equality function for each column being compared --- they used to do bitwise comparisons or convert the data to text strings and strcmp(). (To add insult to injury, they'd look up the conversion functions once for each tuple...) Parse/plan representation of DISTINCT is now a list of SortClause nodes. initdb forced by querytree change...

| | | | | | Fewer calls to nameout. Better use of RelationGetRelationName.
* Several changes here, not very related but touching some of the same files.Tom Lane1999-09-241-98/+74
| | | | | | | | | | | | | | | | | | | | | * 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.
