CAST from VARCHAR to INT

(Postgres 7.2.1)

I screwed up when I was designing a table a while back and made a column a
VARCHAR that referenced (and should have been) an INT.

Now I'm trying to correct my mistake, I've created a new table and I'm
trying to INSERT INTO...SELECT the data into it, but it's complaining that
it can't stick a VARCHAR into an INT. All the values in the column are valid
integers (the foreign key sees to that) but even a CAST won't do it.

How can I force it to copy/change the values?
