Per-table level? Some of the problems that have been put forward have to do with table combinations (for example selectivity of joins), so not all problems will be solved with a per-table design. I think if it were per table, you could get away with storing stuff in pg_statistics or some such. But how do you express statistics for joins? How do you express cross-column correlation? -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
