Support for psycopg3

[Dilski]

It would be nice to have patching/tracing support for psycopg3.
This project already supports psycopg2, but with the package using a different name (not just a new major package version), I do not think the patching works with psycopg3

I am happy to try to implement this, with support

A fix for this would be really appreciated.

I believe this is now implemented, but not contained in a release yet
