I think this is a GREAT idea, but this line made me laugh[1]:
+ warn "No Natts defined yet, silently skipping check...\n";
I suggest that we make that a fatal error. Like "Could not find
definition Natts_pg_proc before start of DATA".
Secondly, I don't think we should check this at this point in the
code, because then it blindly affects everybody who uses Catalog.pm.
Let's pick one specific place to do this check. I suggest genbki.pl,
inside the loop with this comment: "# Ordinary catalog with DATA
line(s)"
