I received this message after running vacuum on a database. NOTICE: number of page slots needed (27296) exceeds max_fsm_pages (20000) HINT: Consider increasing the configuration parameter "max_fsm_pages" to a value over 27296. The documentation for 8.1 sates: This setting must be more than 16 * max_fsm_relations. The default is 20000. This option can only be set at server start. Do I increase max_fsm_pages or max_fsm_relations, or both. Does "only be set at server start" mean to alter the settings in postgresql.conf and then restart the postmaster?
