PG is really difficult to contribute to because it's such a fast moving target. You get your patches into one commitfest and then you don't get them accepted in time, now you're into the next commitfest, and now you have to rebase across 1,000 commits, lather, rinse, repeat.

Contributing to PG is nearly a full-time job!

I bet it's much easier to find an existing committer to PG and pay them as consultants to do the work you need.

And as siblings point out, you have to figure out what the upstream might be willing to accept, and they might have to tell you that. This requires a conversation. Presenting to them is a way to start that conversation.
