You're correct -- we also crash on extremely long SELECT statements.
Another variant of the problem would be a CREATE TABLE that inherits
from, say, 70 relations, each of which has 1,000 columns.
Attached is a patch. Not entirely sure that the checks I added are in
the right places, but at any rate this fixes the three identified
problems for me.
