PostgreSQL 14+ will support a `BIT_XOR` aggregate function. We already
support `BIT_AND` and `BIT_OR` in `django.contrib.postgres`.
See https://www.postgresql.org/docs/release/14.0/
----
As an aside, it looks as though Oracle 21c supports these as
`BIT_AND_AGG`, `BIT_OR_AGG`, and `BIT_XOR_AGG`.
They're also supported in MySQL and MariaDB, but when there are no rows to
aggregate they don't return `NULL`.
It's relative straightforward to register custom aggregates for SQLite for
these too.
Perhaps there might be a case to migrate these to
`django.db.models.aggregates` in the future...
