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.

* 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.
