This module exists to avoid a circular import problem: pyscopg2.extras depends
on psycopg2.extension, so I can't create the default JSON typecasters in
extensions importing register_json from extras.

An `~psycopg2.extensions.ISQLQuote` wrapper to adapt a Python object to
:sql:`json` data type.
`!Json` can be used to wrap any object supported by the provided *dumps*
function. If none is provided, the standard :py:func:`json.dumps()` is
used.

The default is to call `!json.dumps()` or the *dumps* function
provided in the constructor. You can override this method to create a
customized JSON wrapper.

:param conn_or_curs: a connection or cursor used to find the :sql:`json`
and :sql:`json[]` oids; the typecasters are registered in a scope
limited to this object, unless *globally* is set to `!True`. It can be
`!None` if the oids are provided
:param globally: if `!False` register the typecasters only on
*conn_or_curs*, otherwise register them globally
:param loads: the function used to parse the data into a Python object. If
`!None` use `!json.loads()`, where `!json` is the module chosen
according to the Python version (see above)
:param oid: the OID of the :sql:`json` type if known; If not, it will be
queried on *conn_or_curs*
:param array_oid: the OID of the :sql:`json[]` array type if known;
if not, it will be queried on *conn_or_curs*
:param name: the name of the data type to look for in *conn_or_curs*
The connection or cursor passed to the function will be used to query the
database and look for the OID of the :sql:`json` type (or an alternative
type if *name* if provided). No query is performed if *oid* and *array_oid*
are provided. Raise `~psycopg2.ProgrammingError` if the type is not found.

Create and register :sql:`json` typecasters for PostgreSQL 9.2 and following.
Since PostgreSQL 9.2 :sql:`json` is a builtin type, hence its oid is known
and fixed. This function allows specifying a customized *loads* function
for the default :sql:`json` type without querying the database.
All the parameters have the same meaning of `register_json()`.

Create and register :sql:`jsonb` typecasters for PostgreSQL 9.4 and following.
As in `register_default_json()`, the function allows to register a
customized *loads* function for the :sql:`jsonb` type at its known oid for
PostgreSQL 9.4 and following versions. All the parameters have the same
meaning of `register_json()`.
