Simon Charette f6405c0b8e Fixed #31965 -- Adjusted multi-table fast-deletion on MySQL/MariaDB.
The optimization introduced in 7acef095d7 did not properly handle
deletion involving filters against aggregate annotations.

It initially was surfaced by a MariaDB test failure but misattributed
to an undocumented change in behavior that resulted in the systemic
generation of poorly performing database queries in 5b83bae031.

Thanks Anton Plotkin for the report.

Fixed #31836 -- Dropped support for JSONField __contains and __contained_by lookups on SQLite.
The current implementation works only for basic examples without
supporting nested structures and doesn't follow "the general principle
that the contained object must match the containing object as to
structure and data contents, possibly after discarding some
non-matching array elements or object key/value pairs from the
containing object".

Ravindar Sharma 18d4eac7fc Fixed #31731 -- Removed unreachable code for resetting sequences of auto-created m2m tables in sequence_reset_sql().
Unreachable because f.remote_field.through is truthy for all m2m
fields.

Resetting sequences of auto-created m2m tables in sequence_reset_sql()
is also unnecessary:
 - in sqlsequencereset since c39ec6dccb
   because auto-created tables are included in model_list,
 - in loaddata because there is no it need to reset sequences for
   models not loaded directly.
 - in create_default_site() because it doesn't have m2m fields.

Stopped adapting DecimalField values to strings on Oracle.
cx_Oracle handles decimal.Decimal.

this change.

Jon Dufresne 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.
