It's not unlikely that the foreground VACUUM was blocking on a lock while autovac did the same work, except that that doesn't explain the length of the pause, nor the lack of disk activity. But I can't make it happen right now, so nevermind until I figure out how to reproduce it ... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
