Have a try with RAISE NOTE or RAISE EXCEPTION
keep in mind that exceptions should be exceptional. So a good idea of
whether to use them is to ask 'Do I expect such error' or 'is an explicit
error useful for the caller'. I'ts often better to just return an empty
relation

Use RAISE. See "Errors and Messages" in the PL/pgSQL documentation.
