1: Is the default work_mem pre-allocated to the Postgres processes - or does it get allocated when needed? Say I have work_mem at 30MB - will Postgres allocate that 30MB on connection, or only when it needed by a query?
2: If work_mem is, say, 30MB, and my query needs 10MB - will Postgres allocate all 30MB, or just the 10MB I need? -- Brad Nicholson 416-673-4106 Database Administrator, Afilias Canada Corp. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
