I failed to duplicate this behavior.  I did this in session A:

regression=# begin;
BEGIN
regression=*# select pg_try_advisory_xact_lock(1);
 pg_try_advisory_xact_lock 
---------------------------
 t
(1 row)

then this in session B:

regression=# select pg_try_advisory_xact_lock(1);
 pg_try_advisory_xact_lock 
---------------------------
 f
(1 row)

No warning...
