That should be virtually instant.
First, the usual suspects: have you run "vacuum analyze" on your table? If
not, do it and try again.
If so, please show us your table structure, index, and query - just fire up
psql and run "\d yourtablename" and "explain <your query>" and send it to us.
Cheers,
Steve
