Remove references to pre-11 versions

I've attached a patch that removes some now redundant messaging about
unsupported versions.

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.

Fair enough. I've updated the patch. However, feel free to ignore if
this marks the thin edge of the wedge.

The text in pg_basebackup.sgml describes behavior that still exists in
pg_basebackup. As long as that behavior exists, we should document it
accurately.
