Why is stats_block_level = off by default? Is there a measurable cost to enabling this? We already have stats_row_level = on, so presumably the overhead of setting stats_block_level to on cannot be any worse than that.
Anybody got any objection to setting it on by default? -- Simon Riggs EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
