An PgSql\Connection instance.
An optional parameter that controls how the returned array is indexed. mode is a constant and can take the following values: PGSQL_ASSOC, PGSQL_NUM and PGSQL_BOTH. Using PGSQL_NUM, pg_get_notify will return an array with numerical indices, using PGSQL_ASSOC it will return only associative indices while PGSQL_BOTH, the default, will return both numerical and associative indices.
An array containing the NOTIFY message name and backend PID. If supported by the server, the array also contains the server version and the payload. Otherwise if no NOTIFY is waiting, then false is returned.
