To avoid breaking extensions, we could leave the typedefs in place with
an #ifndef guard on some symbol that's only defined when building
postgres itself, but not when building extensions (or vice versa with an
#ifdef instead).

This is used a lot in Perl for things we don't want to use in core any
more, but we don't want to break CPAN modules still using.
