 `SearchVector` was changed in Django 2.2 to allow querying non-text fields
 (#29582) by using `CONCAT` which automatically cast such fields to text
 and deals with `NULL` value appropriately.

 This had the unintended side effect of making the generated SQL loose it's
 `IMMUTABLE` status as `CONCAT` can generate locale/TZ dependant output
 which makes the generated SQL expression impossible to index against.
