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. Matthew T. O'Connor

Todo Items for pg_autovacuum client
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. Matthew T. O'Connor

_create a FSM export function and see if I can use it for pg_autovacuum
_look into possible benifits of pgstattuple contrib work
_Continue trying to reduce server load created by polling.
Done:

_Check if required pg_stats are enables, if not exit with error
_Reduce the number connections and queries to the server
_Make database adding and removal part of the normal loop
_make table adding and removal part of the normal loop
_Separate logic for vacuum and analyze
_all pg_autovacuum specific functions are now static
_correct usage of snprintf
_reworked database and table update functions, now they
use the existing database connection and only one query
_fixed -h option output
_cleanup of 'constant == variable' used much more consistently now.
_Guarantee database wide vacuum prior to Xid wraparound
_change name to pg_autovacuum
_Add proper table and database removal functions so that we can properly
clear up before we exit, and make sure we don't leak memory when removing tables and such.
