not forced out-of-line unless that is necessary to make the row fit on a
page. Previously, they were forced out-of-line if needed to get the row
down to the default target size (1/4th page).

The English FAQ has been moved to the wiki, so the translated versions should
have been removed at that point as well.
The FAQ_MINGW.html should have been removed when the platform FAQs were
integrated into the documentation (or earlier).

random number seed each time. This is how it used to work years ago, but
we got rid of the seed reset because it was resetting the main random()
sequence and thus having undesirable effects on the rest of the system.
To fix, establish a private random number state for each execution of
geqo(), and initialize the state using the new GUC variable geqo_seed.
People who want to experiment with different random searches can do so
by changing geqo_seed, but you'll always get the same plan for the same
value of geqo_seed (if holding all other planner inputs constant, of course).
The new state is kept in PlannerInfo by adding a "void *" field reserved
for use by join_search hooks. Most of the rather bulky code changes in
this commit are just arranging to pass PlannerInfo around to all the GEQO
functions (many of which formerly didn't receive it).

Set up proper makefile dependencies in the documentation build rules,
especially around the HTML/index build. The problem we've had with all
previous solutions is that we have used the same file name, such as HTML.index
or bookindex.sgml, to mean different things at different stages of the build,
and make can't distinguish that. The solution here is that the first jade run
produces HTML.index, but does not require bookindex.sgml at all, and produces
no other html output (the latter an idea from Alvaro). The second jade run
includes bookindex.sgml, but does not recreate HTML.index. That way, when you
change an sgml file, jade is run twice and at the end all dependencies are
satisfied. Omitting the html output in the first stage also makes the full
build a lot faster.
When you run one of the print format targets, only the first jade run is run,
then the print target-specific commands. If an HTML build has completed
previously, the first jade run is skipped because the dependencies have
already been satisfied.
The draft and check targets for quick builds and syntax verification are still
there.
update documentation accordingly. This is required in order to have support
for a reentrant scanner. I'm committing this bit separately in order to have
an easy reference if we later decide to make the minimum something different
(like 2.5.33).
as noted by Sebastien Flaesch. Also update the claim that we simply throw
away fields outside this set --- that got changed later to only discard
less-significant fields.
For character types with typmod, character_octet_length columns in the
information schema now show the maximum character length times the
maximum length of a character in the server encoding, instead of some
huge value as before.
but the cure appears to be worse than the disease. It turns out that GNU
tar versions 1.14.x misinterpret -o as --same-owner, not --no-same-owner,
leading to exactly the wrong behavior for both root and nonroot users.
While that bug has been fixed for nearly five years, these tar versions
are still found in the wild, notably in OS X 10.4. Given that #4883 was
the first complaint we'd heard, it's definitely not worth fixing at the
risk of breaking things for other users. Perhaps revisit at a later date
when we're not up against a release deadline.
file to be a symlink. We tried to fix this issue with an earlier server-side
patch, but it didn't fix the whole issue.
The same bug is present in older releases as well, but the 8.4 train is
about to leave the station, and I'm not sure if have consensus on whether
we can remove the -l option in back-branches or do we need to attempt a
server-side fix to make symlinking safe.
Patch by Simon Riggs, per discussion on bug identified by Fujii Masao.
used to work as intended, but got broken some time ago (a quoted empty string
is not an empty string), and got broken some more by the changes to generate
ecpg's preproc.y automatically. Given all the unprotected uses of $(PERL)
elsewhere, it seems best to make use of the $(missing) script rather than
trying to ensure each such use is protected individually. Also fix various
bits of documentation that omitted to mention Perl as a requirement for
building from a CVS pull. Per a complaint from Robert Haas.
ArrayBuildState, per trouble report from Merlin Moncure. By adopting
this fix, we are essentially deciding that aggregate final-functions
should not modify their inputs ever. Adjust documentation and comments
to match that conclusion.
In particular, always show 0 for the date type instead of null, and show
6 (the default) for time, timestamp, and interval without a declared
precision. This is now in fuller conformance with the SQL standard.
Also clarify the documentation about this.

The original implementation of the 3-argument form of get_raw_page() risked
core dumps if the 8.3 SQL function definition was mistakenly used with the
8.4 module, which is entirely likely after a dump-and-reload upgrade. To
protect 8.4 beta testers against upgrade problems, add a check on PG_NARGS.
In passing, fix missed additions to the uninstall script, and polish the
docs a trifle.
