Well, I'd imagine that we've checked CREATE TABLE et al. with
somewhat-too-large values (like 2000 columns), which wouldn't be
sufficiently large to trigger the problem.

Not sure.

I'm always in favour of more regression tests -- patches are welcome :)

That said, there are some minor logistical problems with testing that a
70,000 column CREATE TABLE doesn't fail (it would be nice not to have to
include all that text in the regression tests themselves).
