alter column from varchar(32) to varchar(255) without view re-creation

Good morning,

I am using PostgreSQL 8.0.15.

Is there a way that I can easily alter column type from varchar(32) to 
varchar(255) but do not have to worry about views dependent on it?

If Psql could support column alter without views' dependencies, that 
will be great!

Thanks a lot,
