I'm wondering if you meant to leave the "#define DEBUG" line at line
34 in the above file?

It seems pretty strange to do:

#define DEBUG
#ifdef DEBUG
#define pg_debug(...)  do { fprintf(stderr, __VA_ARGS__); } while (0)
#else
#define pg_debug(...)
#endif

pg_debug will never be an empty macro.

I noticed this when testing compiling postgres with MSVC. The compiler
is kicking out a warning: 'DEBUG': macro redefinition, which will be
because that compiler defines DEBUG when doing non-production builds.
