+Predicate pushdown support
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The connector does not support pushdown of inequality predicates, such as
+``!=``, ``>``, or ``BETWEEN``, on columns with
+:ref:`character string types <string-data-types>` like ``CHAR`` or ``VARCHAR``.
+Equality predicates, such as ``IN`` or ``=``, on columns with textual types are
+pushed down. This ensures correctness of results since the remote data source
+may sort strings differently than Trino.
+
+In the following example, the predicate of the first query is not pushed down
+since ``name`` is a column of type ``VARCHAR`` and ``>`` is an inequality
+predicate. The second query is pushed down.
+
+.. code-block:: sql
+
+    SELECT * FROM nation WHERE name > 'CANADA';
+    SELECT * FROM nation WHERE name = 'CANADA';

+Predicate pushdown support
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The connector does not support pushdown of any predicates on columns with
+:ref:`textual types <string-data-types>` like ``CHAR`` or ``VARCHAR``.
+This ensures correctness of results since the data source may compare strings
