Comment (by Adam (Chainz) Johnson):
😟 Hmm this is a tough one.
psycopg2 uses `type(obj)` to look for its "adapter" - in its C extension:
https://github.com/psycopg/psycopg2/blob/e14e3385b4809ec4223894f8c7a009b1560eb41d/psycopg/microprotocols.c#L151
. So this "proxy" approach may not be feasible.
I know of a more accurate proxy wrapper that proxies more attributes than
Django's lazy objects - wrapt.ObjectProxy -
https://wrapt.readthedocs.io/en/latest/wrappers.html#object-proxy. But
docs there acknowledge that it can't even make `type()` work, whilst it
makes `isinstance()` work.
Any ideas of alternative approaches?
