I don't like this interface.  It's nice for psql, but everybody else is
going to lose.  I think these should be reported in the SRF result set
as well; perhaps add a "mode" column that says "skipped" for such rows,
and "matched" for the one that, uh, matches.  (Please try calling your
function with "select * from" which should give nicer output.)
