I didn’t see any past references to the pg_notify() ‘anomaly’:

LISTEN FOO;
NOTIFY FOO, ‘BAR’; -- notification delivered
PERFORM pg_notify(‘FOO’, ‘BAR’); -- notification NOT delivered
PERFORM pg_notify(‘foo’, ‘BAR’); -- notification delivered

Can we come to some agreement on if we should consider this a bug?
