* R-tree is dead ... long live GiST.Tom Lane2005-11-07

* Standard pgindent run for 8.1.Bruce Momjian2005-10-15

* Revise pgstats stuff to fix the problems with not counting accessesTom Lane2005-10-06
| | | | | | | generated by bitmap index scans. Along the way, simplify and speed up the code for counting sequential and index scans; it was both confusing and inefficient to be taking care of that in the per-tuple loops, IMHO. initdb forced because of internal changes in pg_stat view definitions.
* First steps towards index scans with heap access decoupled from indexTom Lane2005-03-27
| | | | | | | | | | access: define new index access method functions 'amgetmulti' that can fetch multiple TIDs per call. (The functions exist but are totally untested as yet.) Since I was modifying pg_am anyway, remove the no-longer-needed 'rel' parameter from amcostestimate functions, and also remove the vestigial amowner column that was creating useless work for Alvaro's shared-object-dependencies project. Initdb forced due to changes in pg_am.
* This patch makes some improvements to the rtree index implementation:Neil Conway2005-01-18
| | | | | | | | | | | | | | | | | | | | | | (1) Keep a pin on the scan's current buffer and mark buffer. This avoids the need to do a ReadBuffer() for each tuple produced by the scan. Since ReadBuffer() is expensive, this is a significant win. (2) Convert a ReleaseBuffer(); ReadBuffer() pair into ReleaseAndReadBuffer(). Surely not a huge win, but it saves a lock acquire/release... (3) Remove a bunch of duplicated code in rtget.c; make rtnext() handle both the "initial result" and "subsequent result" cases. (4) Add support for index tuple killing (5) Remove rtscancache(): it is dead code, for the same reason that gistscancache() is dead code (an index scan ought not be invoked with NoMovementScanDirection). The end result is about a 10% improvement in rtree index scan perf, according to contrib/rtree_gist/bench.
* Tag appropriate files for rc3PostgreSQL Daemon2004-12-31
| | | | | | | | Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

* More janitorial work: remove the explicit casting of NULL literals to aNeil Conway2004-01-07

* Restructure indexscan API (index_beginscan, index_getnext) perTom Lane2002-05-20
| | | | | | | yesterday's proposal to pghackers. Also remove unnecessary parameters to heap_beginscan, heap_rescan. I modified pg_proc.h to reflect the new numbers of parameters for the AM interface routines, but did not force an initdb because nothing actually looks at those fields.
