Err, no, sorry if you thought it was. If you still want to volunteer
I'm sure it'd be more than welcome.

No, I don't think pg_filedump is a good host for such checks. If we're
going to have a tool to do that it'd be better to be able to include it in
core (or at least contrib), and we can't have pg_filedump in there for
licensing reasons.
