After some reflection, I committed the middle patch ("Swap order of
extern/static and pg_nodiscard") after all. The code comment about the
provenance of the name needed updating anyway, and it made sense in that
context to adjust the order to make it more future-proof and make it
consistent with pg_noreturn.

I'll leave the last patch out for now, though.
