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.


If you did that, you'd have a char field padded out to fill up 10 megabytes-worth of characters.  I doubt that's what you want.

It's not clear what you want this for though.  If you want an arbitrary number of characters, just use the text data type.
