`iexact` and other text-lookups should work on
[https://github.com/django/django/blob/492ed60f236d770eb9a6d56d85ff2550bb1ecfff/django/contrib/postgres/fields/hstore.py#L79-L88
key transforms] on `HStoreField` because it returns `TextField`. Maybe
it's enough to add a similar note to the one about `JSONField`, e.g.:
{{{
.. note::
Key transforms can also be chained with: :lookup:`contains`,
:lookup:`icontains`, :lookup:`endswith`, :lookup:`iendswith`,
:lookup:`iexact`, :lookup:`regex`, :lookup:`iregex`,
:lookup:`startswith`,
and :lookup:`istartswith`.
}}}
This is untested so some tests will also be required.
