Re: Autovacuum deadlock - bug or not?

Unfortunately, relfilenodes 68950 and 68122 don't exist anymore, could be t=
hat they were temporary copies of tables or indexes. I know that process 15=
865 was the autovacuum pid, I looked that up when it happened (pg was resta=
rted with autovacuum=3Doff afterwards, so that process is also gone)

Could it be that the deadlock was caused by autovacuum trying to vacuum one=
 of the temp copies?

Hmph.  Looking at the code, that should always lock the table first,
so I don't see where the problem is.  Would you look up the numbers
for us --- exactly which relations were involved in the deadlock,
and (if you can tell) which process was which?

Also, what PG version is this exactly?
