Which PG version is this, and do you have autovacuum enabled?  Awhile
back it was possible to get this error if autovac and a manual vacuum
hit the same table concurrently (the error actually stems from trying
to update pg_statistic concurrently during the ANALYZE phase).

[ squint... ]  That shouldn't happen.  Look into pg_locks to see if
you can determine who's waiting for what.
