Hmmm, this is interesting. Does the cpu time match when the same queries
are run through PSQL?

You know, I also noticed that it is the postgres back-end process which
is
using all the CPU time during the query. Doesn't sound like Vector
operations to me, which should cause the java process to eat all the CPU
time.
