7cce39c7ce The following patch should allow UPDATE_INTERVAL to be specified on the
command line. We find this useful because we frequently deal with
thousands of tables in an environment where neither the databases nor
the tables are updated frequently. This helps allow us to cut down on
the overhead of updating the list for every other primary loop of
pg_autovacuum.

I chose -i as the command-line argument and documented it briefly in
the README.

The patch was applied to the 7.4.7 version of pg_autovacuum in contrib.

This was fixed in v1.21 of pg_autovacuum.c, That rev is tagged for
beta3, so you should not be seeing this issue unless you actually have
an older version for some reason.

It's not so much that it strips them (that happens automagically), more
that it doesn't re-add them when it writes the command line in the
registry. The attached patch fixes that by simply quoting all options
that may need it.

A -E <service> option is added in the attached patch.

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.

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...

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.

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.
