-``datasette`` - :ref:`internals_datasette`
-    You can use this to access plugin configuration options via ``datasette.plugin_config(your_plugin_name)``, or to execute SQL queries.
-
-``database`` - string
-    The name of the database.
-
-``actor`` - dictionary or None
-    The currently authenticated :ref:`actor <authentication_actor>`.
-
-Use this hook to return a dictionary of additional :ref:`canned query <canned_queries>` definitions for the specified database. The return value should be the same shape as the JSON described in the :ref:`canned query <canned_queries>` documentation.

-                }
-            }
-
-The hook can alternatively return an awaitable function that returns a list. Here's an example that returns queries that have been stored in the ``saved_queries`` database table, if one exists:
-
-.. code-block:: python
-
-    from datasette import hookimpl
-
-
-    @hookimpl
-    def canned_queries(datasette, database):
-        async def inner():
-            db = datasette.get_database(database)
-            if await db.table_exists("saved_queries"):
-                results = await db.execute(
-                    "select name, sql from saved_queries"
-                )
-                return {
-                    result["name"]: {"sql": result["sql"]}
-                    for result in results
-                }
-
-        return inner
-
-The actor parameter can be used to include the currently authenticated actor in your decision. Here's an example that returns saved queries that were saved by that actor:
-
-.. code-block:: python
-
-    from datasette import hookimpl
-
-
-    @hookimpl
-    def canned_queries(datasette, database, actor):
-        async def inner():
-            db = datasette.get_database(database)
-            if actor is not None and await db.table_exists(
-                "saved_queries"
-            ):
-                results = await db.execute(
-                    "select name, sql from saved_queries where actor_id = :id",
-                    {"id": actor["id"]},
-                )
-                return {
-                    result["name"]: {"sql": result["sql"]}
-                    for result in results
-                }
-
-        return inner
+This hook has been removed. Plugins that need to add saved queries should use
+the :ref:`plugin_hook_startup` hook and call ``await datasette.add_query(...)``.
