Actually, no, it doesn't.
pg_autovacuum will "crap out" if pointed at a 7.2.x instance. It
seems most likely that the cause is some changes to the pg_ tables
between the versions; I haven't found the Round Tuits to dig deeply
into it. I no longer have any 7.2 instances I am concerned about for
autovacuum, so I in a sense "don't care" anymore...
If I had the "round tuits," what I'd rather do is to create a daemon,
probably in Perl/Python, that is up to the task of managing a whole
cluster of backends... That is VERY different from the common desire
for something integrated tightly into the back end; I can foresee
value to both approaches...
