Postgres has gotten incrementally smarter about this, but at the end
of the day it's just working under what the jdbc driver is telling it
what to do. One thing you can do is disable sever-side prepared
statements with the prepareThreshold=0 decoration to the jdbc url give
that a whirl and see how it turns out.
