Bug reference: 1083
Logged by: Martin Langhoff

Description: Insert query reordering interacts badly with
NEXTVAL()/CURRVAL()
Details:
=== SQL ===
CREATE TEMP TABLE testing (col_a integer, col_b integer);
CREATE TEMP SEQUENCE seq;
/* this statement will produce the expected result */
INSERT INTO testing (col_a, col_b) VALUES (NEXTVAL('seq'), CURRVAL('seq'));
/* this statement will reverse the order of CURRVAL()/NEXTVAL() to match the
column order of the table */
INSERT INTO testing (col_b, col_a) VALUES (NEXTVAL('seq'), CURRVAL('seq'));
SELECT * FROM testing;
=== END SQL ===
Output looks like:
col_a | col_b
-------+-------
1 | 1
1 | 2
I was expecting:
col_a | col_b
-------+-------
1 | 1
2 | 2
