Hi All;

We have a client running Pentaho to migrate data.

They recently upgraded Pentaho which upgraded their JDBC driver from 8.4
(postgresql-8.4-703.jdbc4.jar) to 9.1 (postgresql-8.4-703.jdbc4.jar).
They have a test set which updates 1000 rows, with the old driver it
takes about 30 seconds, but the new driver takes 3x longer.

This is on PostgreSQL 9.1

Thoughts?

Thanks in advance...
