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.

MySQL 8.0.3 added support for this syntax but also imposed a
restriction against ALTER TABLE RENAME on tables in a foreign key
relationship if a LOCK TABLES was active which has been lifted in MySQL
8.0.4+.

Fixed #31376 -- Optimized nulls ordering when possible on SQLite and MySQL.
...
Both backends order NULLs first on ascending ordering and last on
descending ordering which makes ORDER BY IS (NOT)? NULL wasteful when
asc(nulls_first) and desc(nulls_last) are used since it prevents indice
usage.
