The connection or cursor passed to the function will be used to query the
database and look for the OID of the |hstore| type (which may be different
across databases). If querying is not desirable (e.g. with
:ref:`asynchronous connections <async-support>`) you may specify it in the
*oid* parameter, which can be found using a query such as :sql:`SELECT
'hstore'::regtype::oid`. Analogously you can obtain a value for *array_oid*
using a query such as :sql:`SELECT 'hstore[]'::regtype::oid`.
Note that, when passing a dictionary from Python to the database, both
strings and unicode keys and values are supported. Dictionaries returned
from the database have keys/values according to the *unicode* parameter.
The |hstore| contrib module must be already installed in the database
(executing the ``hstore.sql`` script in your ``contrib`` directory).
