Adding external python functions to zope is painless.  You put the .py file
in the Extensions directory and add a "ExternalMethod" from the web
management interface.  

You can also wrap python classes around queries, i.e. to calculate
results from the raw data in the database, and make it look like there
are extra columns.  They call these "Pluggable Brains" of all things.

Zope will provide a persistant connection to the database, and can
optionally cache results.  There are some newer PostgreSQL adapters
that are supposed to be thread safe, so you can one PostgreSQL
connection per thread, with a thread pool to handle requests.

Zope does take a while to get your head around.
