Well, sure. ANALYZE puts new rows into pg_statistic, and obsoletes old ones. You need to vacuum pg_statistic every so often (not to mention the other system catalogs). > If we do plain simple "vacuum <tablename>" (again no full), we see > pg_statistics_relid_att_index relfilenode grew instead of > pg_statistics. Don't think I believe that. Plain vacuum won't touch pg_statistic at all (unless it's the target table of course). I'd expect ANALYZE to make both the stats table and its index grow, though. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
