System Configuration
---------------------
Architecture (example: Intel Pentium) : Intel Pentium Pro
Operating System (example: Linux 2.0.26 ELF) : Linux 2.2.14 ELF
PostgreSQL version (example: PostgreSQL-6.5.3): PostgreSQL-6.5.3
Compiler used (example: gcc 2.8.0) : egcs 1.1.2
Please enter a FULL description of your problem:
------------------------------------------------
When inserting new rows into a table with a serial field, if a constraint
check fails, the sequence for the serial field is still incremented. As a
result you lose a number.
Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
1) CREATE TABLE dummy (id serial, other int4 NOT NULL CHECK(other <> 0));
2) INSERT INTO dummy (other) VALUES(1);
3) INSERT INTO dummy (other) VALUES(2);
4) INSERT INTO dummy (other) VALUES(0);
5) INSERT INTO dummy (other) VALUES(3);
6) SELECT * FROM dummy;
You'll see the following:
id other
-- -----
1 1
2 2
4 3
