Yeah, they're all documented in the pgsql-committers archives. Let's see... 2005-08-19 20:39 tgl * src/: backend/access/heap/heapam.c, backend/commands/async.c, backend/commands/trigger.c, backend/commands/vacuum.c, backend/executor/execMain.c, backend/utils/time/tqual.c, include/access/heapam.h, include/access/htup.h, include/executor/executor.h, include/utils/tqual.h: Repair problems with VACUUM destroying t_ctid chains too soon, and with insufficient paranoia in code that follows t_ctid links. (We must do both because even with VACUUM doing it properly, the intermediate state with a dangling t_ctid link is visible concurrently during lazy VACUUM, and could be seen afterwards if either type of VACUUM crashes partway through.) Also try to improve documentation about what's going on. Patch is a bit bulky because passing the XMAX information around required changing the APIs of some low-level heapam.c routines, but it's not conceptually very complicated. Per trouble report from Teodor and subsequent analysis. This needs to be back-patched, but I'll do that after 8.1 beta is out. 2005-06-25 18:47 tgl * doc/src/sgml/backup.sgml, src/backend/commands/dbcommands.c (REL8_0_STABLE), doc/src/sgml/backup.sgml, src/backend/commands/dbcommands.c: Force a checkpoint before committing a CREATE DATABASE command. This should fix the recent reports of "index is not a btree" failures, as well as preventing a more obscure race condition involving changes to a template database just after copying it with CREATE DATABASE. 2005-05-31 15:10 tgl * src/backend/access/transam/: xlog.c (REL7_3_STABLE), xlog.c (REL7_4_STABLE), xlog.c (REL7_2_STABLE), xlog.c (REL8_0_STABLE), xlog.c: Add test to WAL replay to verify that xl_prev points back to the previous WAL record; this is necessary to be sure we recognize stale WAL records when a WAL page was only partially written during a system crash. I seem to recall another one, but am not seeing it in the logs right now. There are also the usual quota of plain old crashing bugs. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
