The consensus on pgsql-release was to unrevert this patch and commit
the fix now, rather than waiting for the next beta. However, the
consensus was also to push the un-revert as a separate commit from the
bug fix, rather than together as suggested by Álvaro. Since time is
short due to the impending release and it's very late where you are,
I've taken care of this. Hope that's OK.

Thanks,
