Maybe it's a stats system issue. No tables have been vacuumed or analyzed today. I had thought that this problem was due to my pg_autovacuum changes, but perhaps not. I restarted PostgreSQL (in production - yikes) About a minute after being restarted, the autovac process fired up. What could get PG in a state where autovac isn't running? Is there anything I should watch to debug or monitor for this problem in the future? I wish I'd noticed whether or not the stats collector process was running before I restarted.
