Sounds like you aren't checking in the part of the parser that resolves
simple variable references.

Don't be silly --- the system catalogs are completely English-centric

meaningless strings? Since the dropped columns should be invisible to
anyone who's not poking at the catalogs, I don't see that we are adding
any cognitive load ...
