Would it be possible to make that macro only defined when building
extensions, but not when building Postgres itself?  For example, Perl
has a PERL_CORE macro that's only defined when building Perl itself, but
not when building CPAN modules, and backwards-compatibility macros and
functions are guarded by `#ifndef PERL_CORE`.
