1ad590541d The attached patch for contrib/pg_autovacuum/README.pg_autovacuum fixes
one apparent error and makes a minor stylistic change that makes it more
consistent and makes clear something that confused me :-)

2678395928 In working through a pg_autovacuum problem with Joe Conway (which turned
out to be the same problem reported by Cott Lang which the previous
patch resolved) a new bug was uncovered when running with a debug level
of greater than 1.

This patch resolves this new found bug and fixes some of the other
debugging output to be more consistent.

Please apply to both HEAD and the 7.4 branch.

ea4b9f14f3 I've run across a pretty serious problem with pg_autovacuum.
pg_autovacuum looses track of any table that's ever been truncated
(possibly other situations too).   When i truncate a table it gets a
new relfilenode in pg_class.  This is a problem because pg_autovacuum
assumes pg_class.relfilenode will join to pg_stats_all_tables.relid.
pg_stats_all_tables.relid is actallly the oid from pg_class, not the
relfilenode.   These two values start out equal so pg_autovacuum works
initially, but it fails later on because of this incorrect assumption.

This patch fixes that problem.  Applied to HEAD and 7.4.X.

15b5d6cfc6 I noticed in the 7.4 release that in contrib/pg_autovacuum, args->logfile is
not initialized if a log file is not specified on the command line.  This
causes an immediate segfault on systems that fill allocated memory with some
value other than zero (my FreeBSD machine uses 0xD0).

Several crashes later I discovered that args->user, password, host, and port
are also used without being initialized.

This doesn't appear to be fixed in CVS and I came up empty on a mailing list
search -- hope it hasn't been reported already.

62fdc3dd60 I have run pg_autovacuum on AIX, so that can, at least loosely, be
considered "tested."

And I have turned all of the 7.4 HISTORY material into DocBook for

I had to make a further change to this to take quotes off the 'last
ANALYZE' in order for it to not overquote the relation name, so
there's a _little_ work left to get it to play well.

I have deployed it onto several boxes that should be doing some
vacuuming over the weekend, and it is now certainly hitting pg_
tables.

I would like to present a CVS-oriented patch; unfortunately, I had to
change the indentation patterns when editing some of it :-(.  The
following _may_ be good; not sure...

3d48045ae1 > It quotes table names for vacuum and analyze, and uppercases the
> keywords for clarity.

Yeah, this is basically what I meant, sorry I didn't get to it quicker.

However, I tested it out a little and the patch you made doesn't work
because it produces commands like:

VACUUM ANALYZE "public.FooBar"

Which doesn't work, so I made my own patch that creates commands like:

VACUUM ANALYZE "public"."FooBar"

This allows for mixed case schema names as well as tables.

Adam, can you please give this a test as you are the person who caught
the bug in the first place.

Thanks,

33ab177a56 Don't assume that struct option is available just because we can find a
getopt_long().  This is more or less the same problem as we saw earlier
with getaddrinfo() and struct addrinfo, and for the same reason: random
user-added libraries might contain the subroutine, but there's no
guarantee we will find the matching header files.

9243664dd4 This patch updates pg_autovacuum in several ways:
* A few bug fixes
* fixes solaris compile and crash issue
* decouple vacuum analyze and analyze thresholds
* detach from tty (dameonize)
* improved logging layout
* more conservative default configuration
* improved, expanded and updated README

please apply and 1st convenience, or before code freeze which ever comes
first :-)

At this point I think I have brought pg_autovacuum and its client side
design as far as I think it should go.  It works, keeping file sizes in
check, helps performance and give the administrator a fair amount
flexibility in configuring it.

Next up is to do the FSM based design that is integrated into the back
end.

p.s. Thanks to Christopher Browne for his help.

cb1672e9f8 Rename README in autovacuum code to match Makefile. 2003-03-23 20:16:06 +00:00
Bruce Momjian
bd18c50ba8 I have updated my pg_autovacuum program (formerly pg_avd, the name
changed as per discussion on the patches list).

This version should be a good bit better.  It addresses all the issues
pointed out by Neil Conway. Vacuum and Analyze are now handled
separately.  It now monitors for xid wraparound.  The number of database
connections and queries has been significantly reduced compared the
previous version.  I have moved it from bin to contrib.  More detail on
the changes are in the TODO file.

I have not tested the xid wraparound code as I have to let my AthlonXP
1600 run select 1 in a tight loop for approx. two days in order to
perform the required 500,000,000 xacts.
