I don't think you'd want that. Remember, work_mem is the amount of memory *per sort*. Queries can request several times that much memory, once per sort they need to perform. You can set it really high, but not 60% of your RAM - that wouldn't be wise. -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
