Note that effective cache size is way simpler. Add up the size of the kernel cache and shared_buffers, set it to that if db is the only thing on the machine. If it shares it then maybe cut it down a bit. It's not a real sensitive setting to a few gigabytes here or there, and allocates nothing, just helps the planner decide teh % chance something is in cache or not. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
