From 91e79260f636ab4d5a43910b6a38bc75651ad14c Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>

Subject: [PATCH] Remove no-longer-required function declarations.
Remove a bunch of "extern Datum foo(PG_FUNCTION_ARGS);" declarations that
are no longer needed now that PG_FUNCTION_INFO_V1(foo) provides that.
Some of these were evidently missed in commit e7128e8dbb305059, but others
were cargo-culted in in code added since then. Possibly that can be blamed
in part on the fact that we'd not fixed relevant documentation examples,
which I've now done.
