Email address:      andreas(dot)kretschmer(at)schollglas(dot)com
PostgreSQL version: 8.1.3

Description:        check constraint

i want to add a check constraint like:

create table foo (i char(7) CHECK (i ~ '^[0-9]{6,7}$'));

i doesn't work, but if works, if i change the type for i to varchar(7).

Bug or feature?
