Hm ... the code in psql's describe.c is not terribly conducive to that.
Parsing of the backslash command, execution of the query/queries, and
presentation of the results is all rather tightly bound up; you'd have
to think about how to decouple those.
If you could do it in a way that didn't result in a quantum jump in
the complexity/unreadability of the code, I think there'd be interest.
