Does PL/PgSQL count as a "language" for your purposes?
PL/PgSQL is built and shipped with the postgreSQL server. It's
essentially always installed. By default it's just not enabled for
access in any database.
The statement:
CREATE LANGUAGE plpgsql;
just tells a given database that PL/PgSQL should be available.
Failing that, you might be able to use an SQL function (though I don't
really see how you'd handle the special case for "and" without a
subquery to obtain a total result count) or write a C extension to do it.
Using PL/PgSQL is certainly the easy way.
