What's the easiest way to change the allowable length of a varchar attribute?

I looked in pg_attribute and noticed that the allowable length of the varchar
(+4 bytes for the actual length, presumably) was the atttypemod attribute of
the pg_attribute relation. Is it safe to change that? I would of course need
to be a superuser.

Regards,
    Jeff
