Actually I read that, but it's complicated... it involves planning and a lot of other stuff I don't even know about... My "solution" I guess would be easier (but, of course, can't be used if you don't have enough work_mem): if heap table <= work_mem copy heap table in mem use that region as it was the real file else do the regular (slow!) cluster I guess this can be worse than the current way of doing it only when the table contains a lot of dead rows; in all other cases I can't see how cluster could ever become faster than a simple table + index scans. Of course, I'm not saying it's "very easy" to implement... but given the tons of ram a lot of people use in the servers, and the fact that work_mem can be set on a per-connection basis, I think it would be nice... -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
