It wouldn't be too hard to write a loop that runs the select statement
and does RAISE NOTICE on each row. Getting that into the psql
formatting would be a little trickier, but I don't see why you
couldn't write a PL/pgsql function to do it. Then you could just call
that function and pass it an SQL query every time you want to do this.
