1: Is index capable of being used on the slaves, or are they just making bad decisions? Try disabling seq scans on the slave servers for testing and see if they can use the index. Use "set enable_seqscan = FALSE;"
If they can't use the index then, then they are likely in the wrong locale, and you'll need to re initdb them to get them to use an index. If they can use the index then we have tuning issue. ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
