Thanks. I applied a minor variation of this trick to the JSON module,
so now it builds/installs/tests cleanly on both REL8_4_0 and HEAD
(though it won't work if you copy contrib/json into a pre-9.1
PostgreSQL source directory and type `make` without USE_PGXS=1).
I also went ahead and renamed uninstall_json.sql to
json--uninstall--0.1.sql (again, it's for pre-9.1 users) and removed
unnecessary trailing spaces.

It's a trivial matter to remove backward compatibility from
contrib/json, if anybody wants me to do it. I can just remove
compat.[ch], */init-pre9.1.* , remove the PREFIX_PGVER trick from the
Makefile, remove a few lines in the source code, and maintain the
backported json module elsewhere. It's just a matter of whether or
not explicit backward-compatibility is desirable in modules shipped
with releases.
