+# second client updates its internal cache of the database schema before
+# executing any queries. Specifically, it does not return a "no such column"
+# or "no such table" error if the table or column in question does exist
+# but was added after the second client loaded its cache of the database
+# schema.
+#
+# Types of schema modifications:
+#
+#   1. Adding a database table.
+#   2. Adding a database view.
+#   3. Adding a database index.
+#   4. Adding a database trigger.
+#   5. Adding a column to an existing table (ALTER TABLE).
