Can be schema-qualified :param pyrange: a `Range` strict subclass, or just a name to give to a new class :param conn_or_curs: a connection or cursor used to find the oid of the range and its subtype; the typecaster is registered in a scope limited to this object, unless *globally* is set to `!True` :param globally: if `!False` (default) register the typecaster only on *conn_or_curs*, otherwise register it globally :return: `RangeCaster` instance responsible for the conversion If a string is passed to *pyrange*, a new `Range` subclass is created with such name and will be available as the `~RangeCaster.range` attribute of the returned `RangeCaster` object. The function queries the database on *conn_or_curs* to inspect the *pgrange* type and raises `~psycopg2.ProgrammingError` if the type is not found. If querying the database is not advisable, use directly the `RangeCaster` class and register the adapter and typecasters using the provided functions.
