I agree with you that generally changing datatypes is a task best left
to the DBA, but in case of CHAR/VARCHAR length and probably NUMERIC
length/precision it would be very nice to have some kind of "syntactic
sugar". Figuring out NUMERIC's atttypmod is not what I'd call trivial,
let alone change it. Sure, it may be for you, but...
