password/group files. Also allow read-only subtransactions of a read-write
parent, but not vice versa. These are the reasonably noncontroversial
parts of Alvaro's recent mop-up patch, plus further work on large objects
to minimize use of the TopTransactionResourceOwner.
SAVEPOINT/RELEASE/ROLLBACK-TO syntax. (Alvaro)
Cause COMMIT of a failed transaction to report ROLLBACK instead of
COMMIT in its command tag. (Tom)
Fix a few loose ends in the nested-transactions stuff.
live backends, the archiver and stats processes never got sent a
kill signal. They'd eventually exit on their own, but not for awhile,
which is a bit annoying when you are trying to replace the executable
file on a platform that doesn't allow removal of busy executables.
Also, tweak main loop logic so that we will perform the background
tasks after select() returns EINTR.
recovery_target_timeline --- otherwise there is no path from the backup
to the requested timeline. This check was foreseen in the original
discussion but I forgot to implement it.
recovered from archive is not corrupt. It's not much but it will catch
one common problem, viz out-of-disk-space.
Also, force a WAL recovery scan when recovery.conf is present, even if
pg_control shows a clean shutdown. This allows recovery with a tar backup
that was taken with the postmaster shut down, as per complaint from
Mark Kirkwood.
timezone database for the system behavior we find ourselves in. Scan
backwards from current time and choose the zone that matches furthest
back. As per discussion a week or so back.
recovery more manageable. Also, undo recent change to add FILE_HEADER
and WASTED_SPACE records to XLOG; instead make the XLOG page header
variable-size with extra fields in the first page of an XLOG file.
This should fix the boundary-case bugs observed by Mark Kirkwood.
initdb forced due to change of XLOG representation.

* Fix help text ordering
* Add back --set-session-authorization to pg_dumpall. Updated the docs
for that. Updated help for that.
* Dump ALTER USER commands for the cluster owner ("pgsql"). These are
dumped AFTER the create user and create database commands in case the
permissions to do these have been revoked.
* Dump ALTER OWNER for public schema (because it's possible to change
it). This was done by adding TOC entries for the public schema, and
filtering them out at archiver time. I also save the owner in the TOC
entry just for the public schema.
* Suppress dumping single quotes around schema_path and DateStyle
options when they are set using ALTER USER or ALTER DATABASE. Added a
comment to the steps in guc.c to remind people to update that list.
* Fix dumping in --clean mode against a pre-7.3 server. It just sets
all drop statements to assume the public schema, allowing it to restore
without error.
* Cleaned up text output. eg. Don't output -- Tablespaces comment if
there are none. Same for groups and users.
* Make the commands to DELETE FROM pg_shadow and DELETE FROM pg_group
only be output when -c mode is enabled. I'm not sure why that hasn't
been done before?!?!
This should be good for application asap, after which I will start on
regression dumping 7.0-7.4 databases.

force relcache rebuild for the other table as well as the column's
own table. Otherwise, already-cached foreign key triggers will stop
working. Per example from Alexander Pravking.
