vacuum delay feature, including updating the docs for Tom's recent
improvements. There is still more work to be done here: for example,
adding some more information on the practical use of cost-based
vacuum delay to the "maintenance" section would probably be a good
idea.
1) Now puts in exactly the same change as the current-cvs mingw code
does. (see
http://cvs.sourceforge.net/viewcvs.py/mingw/runtime/mingwex/dirent.c?r1=
1.3&r2=1.4, second part of the patch).
2) Updates both xlog.c and slru.c in backend/access/transam/
3) Also updates pg_resetxlog, which also uses readdir() and checks the
errno value after the loop.

Win2K, and possibly all Win32 variants, it is always 0). This causes a
number of problems in the dfmgr.c logic, which basically all revolve
around the fact that *any* two files will appear to have the same inode.

In incorperates changes from myself and a number of contributors.
This update to dbmirror provides:
-replication of sequence operations via setval/nextval
-DBMirror.pl support for logging to syslog
-changed the names of the tables to dbmirror_* (no quotes required)
-Support for writitng SQL statements to files instead of directly to
a slave database
-More options for DBMirror.pl in the config files.

corner cases that could stand improvement, but it does all the basic
stuff. A byproduct is that the selectivity routines are no longer
constrained to working on simple Vars; we might in future be able to
improve the behavior for subexpressions that don't match indexes.
This commit teaches ANALYZE to store such stats in pg_statistic, but
nothing is done yet about teaching the planner to use 'em.
Also, repair longstanding oversight in separate ANALYZE command: it
updated the pg_class.relpages and reltuples counts for the table proper,
but not for indexes.
vs. timestamptz. This allows use of indexes for expressions like
datecol >= date 'today' - interval '1 month'
which were formerly not indexable without casting the righthand side
down from timestamp to date.
Nov 2002: when constant-expression simplification removes all the
aggregate function calls from a query, that doesn't mean we can act as

indexes, it seems like we ought to put another layer of indirection
between the compute_stats functions and the actual data storage. This
would allow us to compute the values on-the-fly, for example.

Oh ... didn't know that you did a backpatch. Sorry

someone asked me about the FK deadlock fix, mentioned in the 7.3.3
release notes as 3rd change:
http://www.postgresql.org/docs/current/static/release-7-3-3.html
Actually, that fix was available with 7.4, not 7.3. Don't know if we can
retroactively change the release-notes though.

A better workaround for the sentence would be something like:
"and it also happens that the user always has permission"
Looks easier to read, I think.
