+#### JSONB
+
+Since version postgresql-extensions 4.4.0 it is possible to using [Postgresql Jsonb](http://www.postgresql.org/docs/9.4/static/datatype-json.html)
+instead of just json. You need to use at least Postgresql 9.4.
+
+To define a jsonb field you only have to define a `Map` field and use the `JsonbMapType` hibernate user type.
+
+```groovy
+import net.kaleidos.hibernate.usertype.JsonbMapType
+
+class TestMapJsonb {
+    Map data
+
+    static constraints = {
+    }
+    static mapping = {
+        data type: JsonbMapType
+    }
+}
+```
+
+The same criterias implemented for Json are valid for Jsonb.
