I create one new type with CREATE TYPE command.

for my type its INTERNALLENGTH is VARIABLE .

but I want to my type behavior similar to char and when I type this query:

CREATE TABLE tbl (col1 NEWTYPE);

then when I write this query, so it get an error for it's length:

insert into tbl values('dd');

its error is :
ERROR: value too long for type character(1)

but my NEWTYPE don't get this error and work similar to varchar.

how I can do it?

I check for char type the bpchar() function. when I work with char type and want to insert one word longest one character so, bpchar() called.

but for my NEWTYPE don't call the newtype() function.

how can I correct this problem?
