during it:
When bgwriter is active, the startup process can't perform mdsync() correctly
because it won't see the fsync requests accumulated in bgwriter's private
pendingOpsTable. Therefore make bgwriter responsible for the end-of-recovery
checkpoint as well, when it's active.
When bgwriter is active (= archive recovery), the startup process must not
accumulate fsync requests to its own pendingOpsTable, since bgwriter won't
see them there when it performs restartpoints. Make startup process drop its
pendingOpsTable when bgwriter is launched to avoid that.
Update minimum recovery point one last time when leaving archive recovery.
It won't be updated by the end-of-recovery checkpoint because XLogFlush()
sees us as out of recovery already.
This fixes bug #4879 reported by Fujii Masao.

this from a redo-function in the relation forks patch. Noticed by Tom Lane

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.

a number of other geometric operators also depend on. It miscalculated the
slope of the perpendicular to the given line segment anytime that slope was
other than 0, infinite, or +/-1. In some cases the error would be masked
because the true closest point on the line segment was one of its endpoints
rather than the intersection point, but in other cases it could give an
arbitrarily bad answer. Per bug #4872 from Nick Roosevelt.
Bug goes clear back to Berkeley days, so patch all supported branches.
Make a couple of cosmetic adjustments while at it.
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.
of the 256KB limit originally enforced by a patch committed 2008-11-06.
Per recent test results, the smaller size resulted in an undesirable decrease
in bulk data loading speed, due to COPY processing frequently getting blocked
for WAL flushing. This area might need more tweaking later, but this setting
seems to be good enough for 8.4.

our pre-8.4 behavior, as per bug #4862.

Add a couple of regression test cases for this. In passing, get rid of the
labeling of the individual test cases; doesn't seem to be good for anything
except causing extra work when inserting a test...

bug in 8.4, but only because prior versions rejected SRFs in an Agg plan
node altogether.
This prevents autovacuum from reclaiming free space in them and causing
the test's output row order to change, which is causing intermittent
bogus failure reports in the buildfarm.
Backpatch to 8.3. The issue exists further back, but since autovacuum was
not on by default before 8.3, it's not a problem for buildfarm testing.
