Hmm, this is an interesting idea. I wonder what would happen if we let other SLRU users go into shared buffers too -- for example it has been reported several times that pg_subtrans thrashing can cause severe problems in case of long running transactions. (I wonder whether pg_subtrans would occupy a big portion of shared buffers if we let it go unchecked). -- Alvaro Herrera http://www.CommandPrompt.com/ PostgreSQL Replication, Consulting, Custom Development, 24x7 support ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
