Subject: Rollback locks table - why?

Message-ID: <20080320134433.259270@gmx.net> (raw)
Hello list,
I am a bit confused. See the code below:
BEGIN;
SAVEPOINT sp1;
INSERT INTO test(id,runde) VALUES(2, 0);
--if there is a unique key violstion:
ROLLBACK TO sp1;
UPDATE test SET id = 1000 WHERE runde = 0;
COMMIT;
When I first run this statement, I do not get any error message, but also there's also no INSERT on table test. If I run just:
INSERT INTO test(id,runde) VALUES(2, 0);
on its own, it works. (i.e. I get a new row). If I run the transaction block from above again I get first a unique key violation (that is ok, because that's what I trying to check for) but there is NO rollback to sp1, only the "Unique Key" error message and after that I get the dreaded "current transaction is aborted" error message and the system reports an EXCLUSIVE LOCK on the table (<IDLE>in transaction).
Any ideas what I am doing wrong?
Using PostGreSQL 8.2.7 on Windows XP.
Regards and many thanks in advance
Jan
