The replication is an exact block-level replication of the master. We can't write very much at all on the slave. So if a query runs slow because of lack of stats you'd need to run ANALYZE on the master, which would then propagate the stats to the slave which could then use them. -- Simon Riggs EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
