It seems like I'll have to decouple autovacuum PGPROC's from autovacuum's own shared memory. The most sensible way to do this seems to be to store them in ProcGlobal, along with the regular backend's PGPROCs. Is everyone OK with this plan? Note that this will mean that those PGPROCs will be protected by the same spinlock that protects the other PGPROCs. I can't think of any reason why this would be a problem, but if you think otherwise please speak up. -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
