Huh? First of all, the documentation says that NOTIFY does take an
argument. Secondly, I tried it in two psql's and it appears to work. I
now understand what the other talk was about, LISTEN is only checked once
after each query (correct?).
Now, as far as slow and ugly, remember that the query could always just be
something like select 1;
