If we want to make that a policy, I think a lot more could be done --- I remember noticing a documentation comment about some 8.x version just recently. However, "out of support" is a lot different from "nobody has any code written for that version anymore". So I'd be inclined to keep the first hunk in your patch, the one explaining the regexp_matches- in-a-subselect trick. People will be trying to puzzle out why somebody did it like that for years to come. I agree with simplifying the other two spots. regards, tom lane
