That won't help for this particular problem, though --- composite types
don't take typmods, and there'd be no mechanism to pass it down to the
varchar field if they did. I don't think the OP can solve his problem
just with spare parts. In 8.3 he could write a primitive type that
behaves the way he wants, but it'd take an annoyingly large amount
of custom C code :-(
