Something like this should do the trick:
DO
$$
DECLARE
rec RECORD;
BEGIN
FOR rec IN
SELECT n.nspname || '.' || p.proname || '(' || pg_catalog.pg_get_function_arguments(p.oid) ||')' AS func
FROM pg_catalog.pg_proc p
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = p.pronamespace
WHERE p.proname LIKE 'foo%'
LOOP
RAISE NOTICE 'Dropping: %', rec.func;
EXECUTE 'DROP FUNCTION ' || rec.func;
END LOOP;
END;
$$;
Use at your own risk etc. etc.
