Maintain v3.x line with psycopg2 support

[winglian]

What action do you want to perform

Since psycopg 3 isn't slated to for GA with SQLAlchemy until their 2.0 release, most users of SQLAlchemy are still using v1.4 with psycopg2. For those of us on SQLAlchemy v1.4, it doesn't really make sense to write tests with this fixture package that requires psycopg 3. Would you be open to maintaining the v3.x line please so that we can continue to get feature upgrades and fixes without the psycopg2 requirement. I'd be happy to help maintain that branch if so.

@winglian the latest release of https://github.com/ClearcodeHQ/pytest-postgresql/tree/v3 branch got backported support for pytest 7. (3.1.3 - https://pypi.org/project/pytest-postgresql/3.1.3/ )

I'm open to backporting fixes to v3, but won't actively pursue it. Not sure if there's something major to get backported though 🤔

Thanks @fizyk. That was exactly what I was looking for. I assumed 3.1.2 was the end of the road for 3.x when I was looking at the changelog in main and I didn't think to look in pypi.

Thanks to you it'll be bit easier to find :)
