pgsql: Revert "Get rid of the "new" and "old" entries in a view's range

Revert "Get rid of the "new" and "old" entries in a view's rangetable."

This reverts commit 1b4d280ea1eb7ddb2e16654d5fa16960bb959566.
It's broken the buildfarm members that run cross-version-upgrade tests,
because they're not prepared to deal with cosmetic differences between
CREATE VIEW commands emitted by older servers and HEAD. Even if we had
a solution to that, which we don't, it'd take some time to roll it out
to the affected animals. This improvement isn't valuable enough to
justify addressing that problem on an emergency basis, so revert it
for now.
