This revert series reverts 5 postgresql commits from earlier today. There seems
to be a handful of rdeps that need to be addressed before removal of
postgresql-13.
With this single revert commit, *this* commit can be reverted in future to
reapply all 5 commits again when the rdeps are sorted out.
This reverts commits:
