PLPG

How do I create a PLPG procedure by means of a statement ?
For instance:

private static String createFunction = "CREATE OR REPLACE FUNCTION
process_audit_customer() RETURNS TRIGGER AS \n"
+ "$process_audit$ \n"
+ "BEGIN \n"
+ "IF (TG_OP = 'DELETE') THEN \n"
+ "INSERT INTO tmp_customer SELECT OLD.*, 'D', now(), user\\; \n"
+ "RETURN OLD\\; \n"
+ "ELSIF (TG_OP = 'UPDATE') THEN \n"
+ "INSERT INTO tmp_customer SELECT OLD.*, 'U', now(), user\\; \n"
+ "RETURN NEW\\; \n"
+ "ELSIF (TG_OP = 'INSERT') THEN \n"
+ "INSERT INTO tmp_customer SELECT NEW.*, 'I', now(), user\\; \n"
+ "RETURN NEW\\; \n"
+ "END IF\\; \n"
+ "RETURN NULL\\; \n"
+ "END\\; \n"
+ "$process_audit$ \n" + "LANGUAGE plpgsql SECURITY DEFINER;";

When I try to execute such statement an exception is raised:

ERROR: unterminated dollar-quoted string at or near "$process_audit$

BEGIN
IF (TG_OP = 'DELETE') THEN
INSERT INTO tmp_customer SELECT OLD.*, 'D', now(), user

Does anybody have a suggestion ?
