With ALLOWNULLCHAR, OpenESQL does not truncate the contents of the input host variable when the first embedded NULL character is encountered.
With NOALLOWNULLCHAR, however, the database is presented a truncated value, including all characters up to the first embedded NULL.
PostgreSQL does not support the embedding of the NULL character into CHAR columns; therefore ALLOWNULLCHAR is not supported in PostgreSQL OpenESQL applications.
