Fixed #30542 -- Fixed crash of numerical aggregations with filter.
...
Filters in annotations crashed when used with numerical-type
aggregations (i.e. Avg, StdDev, and Variance). This was caused as the
source expressions no not necessarily have an output_field (such as the
filter field), which lead to an AttributeError: 'WhereNode' object has
no attribute output_field.
Thanks to Chuan-Zheng Lee for the report.

Used time.monotonic() instead of time.time() where applicable.
...
time.monotonic() available from Python 3.3:
- Nicely communicates a narrow intent of "get a local system monotonic
clock time" instead of possible "get a not necessarily accurate Unix
time stamp because it needs to be communicated to outside of this
process/machine" when time.time() is used.
- Its result isn't affected by the system clock updates.
There are two classes of time.time() uses changed to time.monotonic()
by this change:
- measuring time taken to run some code.
- setting and checking a "close_at" threshold for for persistent db
connections (django/db/backends/base/base.py).

Fixed #30349 -- Fixed QuerySet.exclude() on FilteredRelation.
...
Using annotated FilteredRelations raised a FieldError when coupled with
exclude(). This is due to not passing filtered relation fields to the
subquery created in split_exclude(). We fixed this issue by passing the
filtered relation data to the newly created subquery.
Secondly, in the case where an INNER JOIN is used in the excluded
subquery, the ORM would trim the filtered relation INNER JOIN in attempt
to simplify the query. This will also remove the ON clause filters
generated by the FilteredRelation. We added logic to not trim the INNER
JOIN if it is from FilteredRelation.

The LIKE operator wildcard generated for contains, startswith, endswith and

Ideally we'd delegate parameters interpolation in DDL statements on backends
that support it but that would require backward incompatible changes to the
Index and Constraint SQL generating methods.
