So ... that's supposed to work, because we have a test script that
verifies that all our headers compile as C++.

Or I thought it was "all", anyway. Closer inspection shows that it's
not checking src/pl. Nor contrib.

I propose that we change src/tools/pginclude/cpluspluscheck so that
it searches basically everywhere:

-for f in `find src/include src/interfaces/libpq/libpq-fe.h src/interfaces/libpq/libpq-events.h -name '*.h' -print | \
+for f in `find src contrib -name '*.h' -print | \

However, trying to run that, I find that plpython and plperl are both
seriously in violation of the project convention that headers should
compile standalone. It looks like most of their headers rely on an
assumption that the calling .c file already included the Python or
Perl headers respectively.

Anybody object to me reshuffling the #include's to make this pass?
I propose doing that for HEAD only, although we should back-patch
George's fix (and any other actual C++ problems we find).
