What happens to NOTICEs in your application?

For some odd reason, deadlock reports come out as a NOTICE followed by
this error message; if you are bit-bucketing NOTICEs then you may well
be confused.


Window 1:

regression=# begin;
BEGIN
regression=# lock int4_tbl;
LOCK TABLE

Window 2:

regression=# begin;
BEGIN
regression=# lock int8_tbl;
LOCK TABLE
regression=# lock int4_tbl;
<< waits >>

Window 1:

regression=# lock int8_tbl;
NOTICE:  Deadlock detected -- See the lock(l) manual page for a possible cause.
ERROR:  WaitOnLock: error on wakeup - Aborting this transaction
