Hi all,
On one hand pg_autovacuum must give opportunity to launch it without sleep
loop, for instance for launch it at night by cron, then it vacuumed only
tables which needed it.
On other, if pg_autovacuum running as daemon, IMHO better launch it from
postmaster, in the same manner, as launched statistic collector.
Must pg_autovacuum also check transaction ID (XID) numbers to prevent
transaction ID wraparound? (PostgreSQL v.7.3.1 docs 8.2.3. Preventing
transaction ID wraparound failures)
And must it reindex in the same manner as contrib/reindexdb? (PostgreSQL
v.7.3.1 docs 8.3. Routine Reindexing)
