Seref, he's suggesting you use TEXT instead of
VARCHAR(something). In PG it's actually usually *less*
overhead to use the unbounded text datatype (no length check
required).
Length checks mandated by business logic can be added by
more dynamic means -- check constraints, triggers, etc which
allow for less invasive change if needed.
