Deprecate pgv4, due to the fact that https://github.com/jackc/pgproto3 is End of Life and no longer supported.

+1 to this approach. We can remove the dependency on pgxv4 without breaking our public API.

Yeah this is good suggestion. Thank you @hessjcg .

Btw, since we are not breaking our API with this approach. We might have to reconsider Major vs Minor upgrade for our release.

This should be a fix commit in my opinion so you can alert users to the change.

With the caveat that the go version change goes in a separate PR.
