Possible, but I think your next suggestion is more likely.

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.
