Yeah, "hiding impromptu documentation inside a test program" is what
this looks like, and I'm not sure that's a reasonable way to go.
(1) Who's going to think to look in src/test/examples/testlibpq3.c for
documentation of binary formats?
(2) The useful details are likely to get buried in notational and
portability concerns, as I think your build failure illustrates.
(3) I bet few if any packagers install these files, so that the new
info would be unavailable to many people.
I think some new appendix in the main SGML docs would be the appropriate
place if we want to provide real documentation.
