seems that you have a very old installation of psycopg2 . upgrade that
and you should be fine (pip install --upgrade psycopg2)
according to docs, server_version was added on psycopg2 2.0.12, and if I'm
not mistaken that should be well before 2 years ago.

it's not that I don't like the use of native js api, but if the tradeoff is
transmitting as base64 that's not an implementation I want to use (given
that there are plenty of "drop-loaders" out there).
Base64 the contents means wasting a net 33% of bandwith.

With the "divs" style, the parent element of the checkboxes is a CAT(),

Hmm, that works for me. Does it work if you do:
db.PhoneNumber.countryTelephoneCode.represent = \
