I may have found the problem; all the hung processes show 'async_notify
waiting' in ps, and the ANALYZE eventually dies with 'tuple concurrently
updated'.
The routine 'ProcessIncomingNotify' in async.c does indeed try to lock
pg_listener (even if we're not using NOTIFY/LISTEN). Not sure why the
ANALYZE is locking the relation, though...but it is locked in AccessShareLock.
I can send a log of my investigations if necessary.
