Uh, then what? The only idea I had was to set a static boolean variable in
syscache.c that controls whether droppped columns are returned, and have
a enable/disable functions that can turn it on/off. The only problem is
that an elog inside a syscache lookup would leave that value set.

My only other idea is to make a syscache that is like ATTNAME except
that it doesn't return a dropped column. I could probably code that up
if you wish.
