named pg_toast_temp_nnn, alongside the pg_temp_nnn schemas used for the temp
tables themselves. This allows low-level code such as the relcache to
recognize that these tables are indeed temporary, which enables various
optimizations such as not WAL-logging changes and using local rather than
shared buffers for access. Aside from obvious performance benefits, this
provides a solution to bug #3483, in which other backends unexpectedly held
open file references to temporary tables. The scheme preserves the property
that TOAST tables are not in any schema that's normally in the search path,
so they don't conflict with user table names.

Per gripe from Eddie Stanley and subsequent discussions with Fabien Coelho
and others.
unlike template0 and template1 does not have any special status in
terms of backend functionality. However, all external utilities such
as createuser and createdb now connect to "postgres" instead of
template1, and the documentation is changed to encourage people to use
"postgres" instead of template1 as a play area. This should fix some
longstanding gotchas involving unexpected propagation of database
objects by createdb (when you used template1 without understanding
the implications), as well as ameliorating the problem that CREATE
DATABASE is unhappy if anyone else is connected to template1.

pghackers discussions.
clause implicitly whenever one is not given explicitly. Remove concept
of a schema having an associated tablespace, and simplify the rules for
selecting a default tablespace for a table or index. It's now just
(a) explicit TABLESPACE clause; (b) default_tablespace if that's not an
empty string; (c) database's default. This will allow pg_dump to use
SET commands instead of tablespace clauses to determine object locations
(but I didn't actually make it do so). All per recent discussions.

Fabien COELHO
the new timetravel.c,
new timetravel.README (cut from spi/README and modified),
modified timetravel.sql.in
and modified timetravel.example.
Features:
- optionally 3 parameter for insert/update/delete user name
- work with CREATE UNIQUE INDEX ixxx on table xxx
(unique_field,time_off);
(the original version was work with unique index on 6.5.0-6.5.3,
and not work on 7.3.2,7.3.3)
(before 6.5.0 and between 6.5.3 and 7.3.2 I dont know)
- get_timetravel(tablename) function for check timetravel-status.
- timetravel trigger not change oid of the active record. (it is not a
good feature, because the old version is automatice prevent the paralel
update with "where oid=nnn")

only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON. Still TODO: provide some client-side autocommit
logic in libpq.
Create objects in public schema.
Make spacing/capitalization consistent.
Remove transaction block use for object creation.
Remove unneeded function GRANTs.
snprintf() in contrib/. I didn't touch the places where pointer
arithmatic was being used, or other areas where the fix wasn't
trivial. I would think that few, if any, of the usages of sprintf()
were actually exploitable, but it's probably better to be paranoid...

malloc()'s. This isn't too serious (because oid2name is a short-lived
utility, so the memory will soon be returned to the OS on process
termination), but I still think it's poor style.
This patch changes oid2name so that it allocates memory on the stack
where possible and free()s the remaining heap-allocated memory. The
patch also fixes a typo a comment and adds 'const' qualifiers to a few
'char *' function parameters.

written a generic framework of rules that the contrib makefiles can
use instead of writing their own each time. You only need to set a few
variables and off you go.
Cygwin with the possible exception of mSQL-interface. Since I don't
have mSQL installed, I skipped this tool.
Except for dealing with a missing getopt.h (oid2name) and HUGE (seg),
the bulk of the patch uses the standard PostgreSQL approach to deal with
Windows DLL issues.
I tested the build aspect of this patch under Cygwin and Linux without
any ill affects. Note that I did not actually attempt to test the code
for functionality.
The procedure to apply the patch is as follows:
$ # save the attachment as /tmp/contrib.patch
$ # change directory to the top of the PostgreSQL source tree
$ patch -p0 </tmp/contrib.patch

> OK, add #include <stdio.h> to the file. That should fix it.
Seems unlikely, since libpq-fe.h already includes <stdio.h>.
The real problem here is that the code is wrong: it's passing NULL
to an int parameter.
