Hi hackers,
Autovacuum uses connections in superuser mode. If all connections are used,
autovacuum cannot start and the following message is written in server log.
| FATAL: sorry, too many clients already
Is this a feature?
The default value of 'superuser_reserved_connections' is 2, so maybe
few people have seen it. Autovacuum can always start in normal use.
(I found it when I tried to make multi-processed autovacuum.)
Regards,
