Can I create a function that returns many records?

I'd like to create a function that outs the results of a select query.
It might work like this:

SELECT METAPHONE('jennifer foobar');
persid | name
-----------------------------
1 | jennifer fubar
10 | gennifer foobar

[I already have the metaphone comparing working, it's the returning
the SELECt that needs help.]

Working through the documentation, I see examples using CREATE
FUNCTION METAPHONE(text) RETURNS setof tblPerson AS 'SELECT
* FROM tblPerson' LANGUAGE 'sql', but this returns only a single
numeric value (that doesn't seem to correspond to anything.)

Is there a way to do this? Any help would be very appreciated.
