Why do we have both the type text and type varchar (without limit)?
Couldn't we make one to be an alias for the other?
Since it's 2 distinct types there are some strange effects:
dennis=> SELECT CAST ('123'::varchar AS integer); ERROR: cannot cast type character varying to integer
dennis=> SELECT CAST ('123'::text AS integer); int4 ------ 123
Sure, the cast is simple to fix. But why do we have two types in the first
place?
