Won't this break extensions that are using pg_restrict? Sure, they
could update their code, but then maybe it wouldn't work anymore
against previous branches. Seems like it'd be better to leave
pg_restrict in place (for awhile anyway) but always #define it
as "restrict". I don't mind ceasing to use it within our own tree
though.
