92d6cff6a2 Fixed #35028 -- Disabled server-side bindings for named cursors on psycopg >= 3. 
While we provide a `cursor_factory` based on the value of the
`server_side_bindings` option to `psycopg.Connection` it is ignored by
the `cursor` method when `name` is specified for `QuerySet.iterator()`
usage and it causes the usage of `psycopg.ServerCursor` which performs
server-side bindings.

Since the ORM doesn't generates SQL that is suitable for server-side
bindings when dealing with parametrized expressions a specialized cursor
must be used to allow server-side cursors to be used with client-side
bindings.

Thanks Richard Ebeling for the report.

Thanks Florian Apolloner and Daniele Varrazzo for reviews.

6a21658163 Refs #33308 -- Modernized database wrapper in the PostgreSQL backend. 
- Used connection.info instead of connection.get_parameter_status() and
  connection.server_info which don't exist in psycopg 3.
- Set encoding using the client_encoding connection parameter instead
  of connection.set_client_encoding() that doesn't exist in psycopg 3.
- Used the dbname connection parameter instead of deprecated
  alias - database.

75410228df Fixed #31473 -- Made sql_flush() use RESTART IDENTITY to reset sequences on PostgreSQL. 
The sql_flush() positional argument sequences is replaced by the boolean
keyword-only argument reset_sequences. This ensures that the old
function signature can't be used by mistake when upgrading Django. When
the new argument is True, the sequences of the truncated tables will
reset. Using a single boolean value, rather than a list, allows making a
binary yes/no choice as to whether to reset all sequences rather than a
working on a completely different set.
