Re: Overhead changing varchar(2000) to text

Thanks.
After reading, I've run some tests and found no storage changes in
tables moving from varchar(2000) to text.
Actually, the biggest change is that I don't have to keep another
constraint between app and database - if I want to increase the user
perceived space, now I just have to change the application (of course,
under the limits).

Atenciosamente,
