Deadlocks ?

Hi All;

we seem to be getting deadlock quite a lot. We have a python process
that does the following and we keep getting deadlocks. Is this a real
deadlock or maybe a wait condition? Any help in debugging / resolving
this would be much appreciated.

Thanks in advance

cursor.execute("lock player_log_uuid in share update exclusive mode")
