a PostgreSQL |range|_ type and a PostgreSQL `Range` subclass.
:param pgrange: the name of the PostgreSQL |range| type. 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.
