Re: Strange DOMAIN behavior

Thank you for your reply.
In fact i want to use domains in the following case:

DROP DOMAIN lexema_str CASCADE;
CREATE DOMAIN lexema_str TEXT DEFAULT 'abc' NOT NULL;
DROP TYPE lexema_test CASCADE;
CREATE TYPE lexema_test AS (
   lex  lexema_str,
   lex2 BIGINT
);
DROP TABLE ttt;
CREATE TABLE ttt (
   a lexema_test,
   b BIGINT
);
INSERT INTO ttt (b) VALUES (1);
SELECT *
FROM ttt;
 a | b
---+---
   | 1
(1 row)

 a.lex is null  again not 'abc' as I expected like in plpgsql.

All i want is to have default values in composite types. Feature that Oracle have.
I thought that with domain type it should be possible.
