The postgres docs say that PHP should never be able to return PGRES_NONFATAL_ERROR "A result of status PGRES_NONFATAL_ERROR will never be returned directly by PQexec or other query execution functions" http://www.postgresql.org/docs/current/static/libpq-exec.html Therefore you cannot use this function to check if this query produced a notice.

If on "accident" your program passes pg_result_status a variable that is NOT a actual pg resource, it will return an empty string. (This is important to know if you want to make sure a pg resource is "good" before attempting some operation on it).
