investigate persistent db connections / db pooling

[allynt]

Maybe look into https://www.pgbouncer.org/ or max_conn_age in settings.py

But see this: https://docs.djangoproject.com/en/5.1/releases/5.1/#postgresql-connection-pools. Django seems to have gone ahead and built this into their framework.

D'oh! That is not compatible w/ psycopg2.

I think I have to use "client pooling" rather than (the simpler) "server pooling" b/c the crappy cheap database package I'm using doesn't support pooling.
