Re: CREATE TYPE similar CHAR type

I want use CREATE TYPE to create one type similar to char.

I want to when I create type, then my type behave similar to char:

CREATE TABLE test (oneChar char);

when I want insert one column with length>1 to it, so it gets this error:
ERROR:  value too long for type character(1)

I want my type behave similar this but it behaves similar varchar type.
