Hi all,

Is it possible to automatically update the sequence after the literal 
value was used in INSERT statement?

For instance,

CREATE SEQUENCE test_table_id;    -- test_table_id = 1
CREATE TABLE test_table (
    id INTEGER NOT NULL DEFAULT nextval('test_table_id') CHECK (id >= 0),
    column1 VARCHAR(255),
    PRIMARY KEY (id)

INSERT INTO test_table (id, column1) VALUES (1000, 'something');

Here, I used literal value for ID (1000), and I want my sequence to be 
updated to 1000 automatically (i.e. without calling setval).

I'm trying to achieve something similar to MySQL's auto_increment feature.
