Description: Some query sequences do not finish

Details:

Hello,

this happens on a database 7.4.3: I have a sequence of 5 commands that I
execute from my Java program. The last of them does never return, so the
program locks. I verified this behaviour with my pgAdmin III 1.0.2 (Linux)
with the same result, the execution time counter runs endlessly, or until I
stop the execution. I had this behaviour with different sequences of
commands, all of them like one "DELETE" command and several "INSERT"
commands. An example:

DELETE FROM EM_ROSTER_1 WHERE ID_COSTCENTER = 525313 AND ID_TOUR = 1049601
AND STARTING_DATE = '2004-8-9';
INSERT INTO EM_ROSTER_1 (COMMENT, ID_COSTCENTER, ID_EMPLOYEE,
