PostgreSQL Daemon	969685ad44	$Header: -> $PostgreSQL Changes ...	2003-11-29 19:52:15 +00:00
Tom Lane	7a3693716d	Reimplement hash index locking algorithms, per my recent proposal to ... pghackers. This fixes the problem recently reported by Markus KrÌutner (hash bucket split corrupts the state of scans being done concurrently), and I believe it also fixes all the known problems with deadlocks in hash index operations. Hash indexes are still not really ready for prime time (since they aren't WAL-logged), but this is a step forward.	2003-09-04 22:06:27 +00:00

Tom Lane	eaeb8621f8	Add some internals documentation for hash indexes, including an ... explanation of the remarkably confusing page addressing scheme. The file also includes my planned-but-not-yet-implemented revision of the hash index locking scheme.	2003-09-01 20:24:49 +00:00
