Values could be 'all' and 'reloption'.
If we don't want to add another GUC, I'll go changing the 'autovacuum' GUC. Values would be: 'on' means enable autovacuum and process all tables, 'off' means disable autovacuum and 'reloption' (?) means only process those tables that have reloption autovacuum_enabled=true. The con is that we couldn't implement a per-{schema,database} switch for autovacuum. So I prefer the first one. -- Euler Taveira de Oliveira http://www.timbira.com/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
