+            follows the column's `type`. The following serialization rules should be
+            taken into account:
+
+            - `BIGINT` values are encoded as JSON numbers in the signed 64-bit integer range.
+            - `DECIMAL` values are encoded as JSON numbers with 64-bit double precision.
+            - `TIMESTAMP` and `DATE` values are encoded as Unix-millisecond integers; a
+              `DATE` resolves to midnight UTC.
+            - `JSON` values are returned as a JSON-encoded string.
+
+            `null` is allowed for any column type where a value is missing.
