That is interesting - both psql and JDBC merely submit statements for the backend to process, so generally you would expect no difference in execution plan or performance. It might be worth setting "log_statement=true" in postgresql.conf and checking that you are executing *exactly* the same statement in both JDBC and psql. regards Mark P.s : lets see the output from EXPLAIN ANALYZE :-) Bill Chandler wrote: >Thanks for the advice. > >On further review it appears I am only getting this >performance degradation when I run the command via >a JDBC app. If I do the exact same query from >psql, the performance is fine.
