a16eedcf9c Fixed #35936 -- Used unnest for bulk inserts on Postgres when possible. 
This should make bulk_create significantly faster on Postgres when provided
only literal values.

Thanks James Sewell for writing about this technique, Tom Forbes for
validating the performance benefits, David Sanders and Mariusz Felisiak
for the review.

7380ac5734 Fixed #35688 -- Restored timezone and role setters to be PostgreSQL DatabaseWrapper methods. 
Following the addition of PostgreSQL connection pool support in
Refs #33497, the methods for configuring the database role and timezone
were moved to module-level functions. This change prevented subclasses
of DatabaseWrapper from overriding these methods as needed, for example,
when creating wrappers for other PostgreSQL-based backends.

Thank you Christian Hardenberg for the report and to
Florian Apolloner and Natalia Bidart for the review.

Regression in fad334e1a9.

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.

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.
