function parameters and dollar quoting in examples; do some polishing
of the existing dollar-quoting docs). The 'how to port from Oracle'
section is looking pretty respectable these days ...
recommend that people go get Apache's rotatelogs program. Additional
benefits are that configuration is done through GUC, rather than
externally, and that the postmaster can monitor the log rotator and
restart it after failure (though we certainly hope that won't happen
often).

subarrays of a given dimension have the same number of elements/subarrays.
Also repair a longstanding undocumented (as far as I can see) ability to
explicitly set array bounds in the array literal syntax. It now can
deal properly with negative array indicies. Modify array_out so that
arrays with non-standard lower bounds (i.e. not 1) are output with
the expicit dimension syntax. This fixes a longstanding issue whereby
arrays with non-default lower bounds had them changed to default
after a dump/reload cycle.
Modify regression tests and docs to suit, and add some minimal
documentation regarding the explicit dimension syntax.
and history files as per recent discussion. While at it, remove
pg_terminate_backend, since we have decided we do not have time during
this release cycle to address the reliability concerns it creates.
Split the 'Miscellaneous Functions' documentation section into
'System Information Functions' and 'System Administration Functions',
which hopefully will draw the eyes of those looking for such things.
number of active subtransaction XIDs in each backend's PGPROC entry,
and use this to avoid expensive probes into pg_subtrans during
TransactionIdIsInProgress. Extend EOXactCallback API to allow add-on
modules to get control at subxact start/end. (This is deliberately
not compatible with the former API, since any uses of that API probably
need manual review anyway.) Add basic reference documentation for
SAVEPOINT and related commands. Minor other cleanups to check off some
of the open issues for subtransactions.

more nearly Oracle-equivalent. Allow matching by category as well as
specific error code. Document the set of available condition names
(or more accurately, synchronize it with the existing documentation). In
passing, update errcodes.sgml to include codes added during 7.5 development.
There are still some things that need refinement; in particular I fear
that the recognized set of error condition names probably has little in
common with what Oracle recognizes. But it's a start.
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.
