Drew,
Not really the answer you were asking, but in general, your
program will probably be using some interface other than
psql, i.e. libpq or Pg.pm, or whatever.
E.g. in C, if your PgQuery struct is pg1, then you
would do your query and retrieve the number of records
found with "pg1->PQntuples(pg1->reply)"
