I was able to cause autovac to crash by repeating contrib/intarray
regression test enough times in a row. The cause is not specific
to autovac, it's a generic bug created by my recent patch to add
"waiting" status to pg_stat_activity. If we block on a lock during
InitPostgres then the stats stuff isn't ready yet ... oops.
Patch committed.
The other issues remain problems however.
