1st, change your log settings log_min_duration_statement to something
like 1000 (one second). This will allow you to see which statements
take the longest.
2nd. Use EXPLAIN ANALYZE on those statements to determine what is
taking a long time and focus on optimizing those statements that take
the longest to execute.
That ought to get you a long way down the road.
