Delete function without knowing the elements

All,

I created a function that I can't seem to delete.

[no sure how many parameters]

CREATE OR REPLACE FUNCTION insertEntry (int4, varchar, varchar, numeric,
varchar, timestamp, varchar, int4, numeric, varchar, int4, ....,....)RETURNS INT4 AS '
.................................................END;
' LANGUAGE 'plpgsql';

How can I delete this without knowing how many I used to create it? This is
what I used to delete others in the past.

DROP FUNCTION insertEntry(int4, varchar, varchar, ...);

Thanks,
-pete
