CREATE SCHEMA s1;
CREATE SCHEMA s2;

CREATE TABLE s1.a1(a int);
CREATE TABLE s2.a1(a int);

CREATE OR REPLACE FUNCTION s1.fx1()
RETURNS int AS $$
BEGIN RETURN (SELECT MAX(a) FROM s1.a1); END
$$ LANGUAGE plpgsql;

CREATE OR REPLACE FUNCTION s2.fx1()
RETURNS int AS $$
BEGIN RETURN (SELECT MAX(a) FROM s2.a1); END
$$ LANGUAGE plpgsql;

SET search_path TO s1;
SELECT fx1(); -- returns max from s1.a1;

SET search_path TO s2;
SELECT fx1(); -- returns max from s2.s1;
