I don't believe any of this. In the first place, if you're not using
LISTEN/NOTIFY then there's no reason for any backend to try to take out
an AccessExclusive lock on pg_listener (which is the only kind that would
be blocked by ANALYZE's measly AccessShareLock). In the second place,
an ANALYZE on a zero-page relation cannot conceivably take half an hour,
unless it's in turn being blocked by something else.
Please dig deeper.
