Yeah, absolutely agreed. But I'm afraid this proposal takes us too
far in the other direction: with this, you *must* have a 100% parseable
and semantically valid function body, every time all the time.

So far as plpgsql is concerned, I could see extending the validator
to run parse analysis (not just raw parsing) on all SQL statements in
the body. This wouldn't happen of course with check_function_bodies off,
so it wouldn't affect dump/reload. But likely there would still be
demand for more fine-grained control over it ... or maybe it could
stop doing analysis as soon as it finds a DDL command?
