OK, it seems that while everyone wants autovacuum be more aggressive by default, no one has any good data to support one setting or another. I so I suggest that we just cut scale factor and base threshold in half right now (so it'd be 0.2, 0.1, 500, 250) and see about a better-researched setting for the next release. -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
