Moving to -hackers
I'm working on getting auto-incrementing CMP fields in JBoss 3.2.1 to
work with PostgreSQL data sources. There are currently two obstacles
to this.
Yeah.. JBoss is very annoying in this regard. A temporary solution seems
to be to use BEFORE triggers to force the sequence

default value. You could also do this with an INSTEAD rule (something
like the below):
CREATE OR REPLACE RULE

CREATE OR REPLACE RULE rulename AS ON INSERT
TO tablename
DO INSTEAD
INSERT INTO tablename
( id, col1, ...)
VALUES ( DEFAULT, NEW.col1, ...);
I now have a patch that adds support for the GENERATED ... AS ...
syntax and
des=# create table test ( id serial, word text );
NOTICE: CREATE TABLE will create implicit sequence test_id_seq for SERIAL column
test.id
CREATE TABLE
des=# create rule test_id_generate as
des-# on insert to test do instead
des-# insert into test ( id, word ) values ( default, new.word
OK, I read further and now understand. Sorry.

CREATE SCHEMA

t=# create rule test_id_generate as on insert to jboss.test
t-# do instead
t-# insert into data.test (id, word) values (default, new.word);
