== Reviews ==
KaiGai Kohei reviewed Robert Haas's patch to add get_whatever_oid
== Applied Patches ==
Peter Eisentraut committed:
- In pgsql/src/interfaces/libpq/fe-connect.c, portability fixes for
Solaris for requirepeer feature patch per report from Dave Page
- Add more checks against altering typed tables. 1. Prohibit altering
column type. 2. Prohibit changing inheritance. 3. Move checks from
Exec to Prep phases in ALTER TABLE code. Backpatched to 9.0
- In pgsql/doc/src/sgml/config.sgml, remove tab from SGML file
- In pgsql/doc/src/sgml/datatype.sgml, tidy up boolean data type page.
- In pgsql/doc/src/sgml/datatype.sgml, fix typo.
- In pgsql/doc/src/sgml/xfunc.sgml, add INSERT statement to example so
that it can be reproduced from John Gage
Robert Haas committed:
- Change the default value of standard_conforming_strings to on. This
change should be publicized to driver maintainers at once and
release-noted as an incompatibility with previous releases.
- Add restart_after_crash GUC. Normally, we automatically restart
after a backend crash, but in some cases when PostgreSQL is invoked
by clusterware it may be desirable to suppress this behavior, so we
provide an option which does this. Since no existing GUC group
quite fits, create a new group called "error handling options" for
this and the previously undocumented GUC exit_on_error, which is now
documented. Review by Fujii Masao.
- Make hstore regression tests independent of
standard_conforming_strings. Per buildfarm.
- Make ECPG regression tests independent of
standard_conforming_strings. Per buildfarm, again.
- Add \conninfo command to psql, to show current connection info.
David Christensen. Reviewed by Steve Singer. Some further changes
- In pgsql/src/bin/psql/command.c, have \conninfo mention the port
even for local sockets. Per discussion with David Christensen,
there can be multiple instances of PG accessible via local sockets,
and you need the port to see which one you're actually connected to.
David's original patch worked this way, but I inadvertently ripped
it out during commit.
- Centralize DML permissions-checking logic. Remove bespoke code in
DoCopy and RI_Initial_Check, which now instead fabricate call
ExecCheckRTPerms with a manufactured RangeTblEntry. This is
intended to make it feasible for an enhanced security provider to
actually make use of ExecutorCheckPerms_hook, but also has the
advantage that RI_Initial_Check can allow use of the fast-path when
column-level but not table-level permissions are present. KaiGai
Kohei. Reviewed (in an earlier version) by Stephen Frost, and by
me. Some further changes to the comments by me.
- Add options to force quoting of all identifiers. I've added a
quote_all_identifiers GUC which affects the behavior of the backend,
and a --quote-all-identifiers argument to pg_dump and pg_dumpall
which sets the GUC and also affects the quoting done internally by
those applications. Design by Tom Lane; review by Alex Hunsaker; in
response to bug #5488 filed by Hartmut Goebel.
- In pgsql/src/bin/pg_dump/pg_dumpall.c, fix bogus server version in
- In pgsql/src/backend/replication/walsender.c, add missing function
prototype. Fujii Masao.
- In pgsql/src/backend/access/transam/xact.c, avoid deep recursion
when assigning XIDs to multiple levels of subxacts. Backpatch to
8.0. Andres Freund, with cleanup and adjustment for older branches
- In pgsql/src/bin/psql/command.c, have psql avoid describing local
sockets as host names. We now use the phrase 'via local socket in'
rather than 'on host' in both \c and \conninfo output, when
applicable. Fujii Masao, with some kibitzing by me.
- CREATE TABLE IF NOT EXISTS. Reviewed by Bernd Helmle.
Bruce Momjian committed:
- Properly replay CREATE TABLESPACE during crash recovery by deleting
directory/symlink before creation. Report from Tom Lane. Backpatch
- Prevent pg_upgrade from migrating databases that use reg* data types
where the oid is not preserved by pg_upgrade (everything but
pg_type). Update documentation. Per bug report from
- In contrib/pg_upgrade, adjust check_for_isn_and_int8_passing_mismatch()
so it is called for all migrations. Backpatch to 9.0.
- In pgsql/doc/src/sgml/ref/create_table.sgml, remove tabs from sgml
Magnus Hagander committed:
- Backpatch reservation of shared memory region during backend startup
on Windows, so that memory allocated by starting third party DLLs
doesn't end up conflicting. The same functionality has been in 8.3
and 8.4 for almost a year, and seems to have solved some of the more
common shared memory errors on Windows.
== Rejected Patches (for now) ==
No one was disappointed this week :-)
== Pending Patches ==

Marc Cousin sent in a patch to correct a cursor declaration in the
"migrating from Oracle" section of the PL/pgsql docs.
Daniele Varrazzo sent in a patch to make more links from the libpq

Mike Fowler sent in another revision of the patch to add XMLEXISTS to
Joseph Adams sent in a patch to add a utf8_to_unicode() function,
similar to the corresponding unicode_to_utf8() function. Among other
things, this smooths the way for the upcoming JSON data type.
