The most likely bottleneck is one due to differences in the queries
actually issued (especially considering that parameters could be
handled differently), such as prepareThreshold issues.
Edit your postgresql.conf and set log_min_duration_statement to zero,
walk through a couple of use cases with the old driver (if possible),
then with the new driver, and compare the durations. If you can't use
the old version anymore at all, just look for the longest durations
with the new driver, or durations corresponding to a particularly slow
form.
