Hm, don't think so. If you've autoconfiscated your client code, you can
just put in a configure test for one of the newer libpq functions.
[ sounds of diff'ing ... ] If you're desperate for an #ifdef solution,
it looks like you could test for the existence of one of the PG_DIAG_XXX
macros added to postgres_ext.h. This seems a bit circuitous though.
