Changing a column's type

Hi All,
    I was using 7.2 and my sequences had a column type of int. I didn't
think much of this until I recently built the RPMs for 7.3 and
"upgraded". i.e. dumped out and imported again. I not that it had all
gone okay until I called a function that was working in 7.2 that is now
broken in 7.3

Reason being is that the column type for the sequence values is now
bigInt and of course I foolishly have a number of functions defined as
taking an INT. So of course the function bails because it can't find a
definition for a function matching bigint.

Anyway, to cut a long story short I was wondering if it is possible to
change the existing type of the sequence columns back to Int or recreate
the sequence with a type of int4.....

And yes, I should probably fix my functions to work with the bigInt
type, but I'm also curious to know if this is possible.

Thanks.
