+# collate3.1.* - Errors related to unknown collation sequences.
+# collate3.2.* - Errors related to undefined collation sequences.
+# collate3.3.* - Writing to a table that has an index with an undefined c.s.
+# collate3.4.* - Misc errors.
+# collate3.5.* - Collation factory.
+#
+
+#
+# These tests ensure that when a user executes a statement with an
