I haven't seen that syntax before. Are you sure you
don't want:

pg_listen dbHandle notifyName callbackCommand

http://www.postgresql.org/docs/7.3/interactive/pgtcl-pglisten.html

are you using some other package, either standalone,
or that wraps around libpgtcl? It almost sounds like
you are using some wrapper package that didn't get
moved to the other machine...
