This is just an example of how to sub-class `LoggingConnection` to
provide some extra filtering for the logged queries. Both the
`initialize()` and `filter()` methods are overwritten to make sure
that only queries executing for more than ``mintime`` ms are logged.
Note that this connection uses the specialized cursor
`MinTimeLoggingCursor`.

registered only on this object unless *globally* is set to `!True`
:param globally: register the adapter globally, not only on *conn_or_curs*
:param unicode: if `!True`, keys and values returned from the database
will be `!unicode` instead of `!str`. The option is not available on
Python 3
:param oid: the OID of the |hstore| type if known. If not, it will be
queried on *conn_or_curs*.
:param array_oid: the OID of the |hstore| array type if known. If not, it
will be queried on *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 |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).
Raise `~psycopg2.ProgrammingError` if the type is not found.

Execute *sql* several times, against all parameters set (sequences or

The function is semantically similar to
.. parsed-literal::
*cur*\.\ `~cursor.executemany`\ (\ *sql*\ , *argslist*\ )
but has a different implementation: Psycopg will join the statements into
fewer multi-statement commands, each one containing at most *page_size*
statements, resulting in a reduced number of server roundtrips.
After the execution of the function the `cursor.rowcount` property will
**not** contain a total result.

:param cur: the cursor to use to execute the query.
:param sql: the query to execute. It must contain a single ``%s``
placeholder, which will be replaced by a `VALUES list`__.
Example: ``"INSERT INTO mytable (id, f1, f2) VALUES %s"``.
:param argslist: sequence of sequences or dictionaries with the arguments
to send to the query. The type and content must be consistent with
*template*.
:param template: the snippet to merge to every item in *argslist* to
compose the query.
- If the *argslist* items are sequences it should contain positional
placeholders (e.g. ``"(%s, %s, %s)"``, or ``"(%s, %s, 42)``" if there
are constants value...).
- If the *argslist* items are mappings it should contain named
placeholders (e.g. ``"(%(id)s, %(f1)s, 42)"``).
If not specified, assume the arguments are sequence and use a simple
positional template (i.e. ``(%s, %s, ...)``), with the number of
placeholders sniffed by the first element in *argslist*.
:param page_size: maximum number of *argslist* items to include in every
statement. If there are more items the function will execute more than
one statement.
:param fetch: if `!True` return the query results into a list (like in a
`~cursor.fetchall()`). Useful for queries with :sql:`RETURNING`
clause.
.. __: https://www.postgresql.org/docs/current/static/queries-values.html
After the execution of the function the `cursor.rowcount` property will
**not** contain a total result.
While :sql:`INSERT` is an obvious candidate for this function it is
possible to use it with other statements, for example::
>>> cur.execute(
... "create table test (id int primary key, v1 int, v2 int)")
>>> execute_values(cur,
... "INSERT INTO test (id, v1, v2) VALUES %s",
... [(1, 2, 3), (4, 5, 6), (7, 8, 9)])
>>> execute_values(cur,
... """UPDATE test SET v1 = data.v1 FROM (VALUES %s) AS data (id, v1)
... WHERE test.id = data.id""",
... [(1, 20), (4, 50)])
>>> cur.execute("select * from test order by id")
>>> cur.fetchall()
[(1, 20, 3), (4, 50, 6), (7, 8, 9)])
