+# This file implements tests for JOINs.
+#
+# The test case output is all generated by PostgreSQL 14.  This test module
+# was created as follows:
+#
+#   1.   Run a TCL script (included at the bottom of this file) that
+#        generates an input script for "psql" that will run man
+#        diverse tests on joins.
+#
+#   2.   Run the script from step (1) through psql and collect the
+#        output.
+#
+#   3.   Make a few minor global search-and-replace operations to convert
+#        the psql output into a form suitable for this test module.
+#
+#   4.   Add this header, and the script content at the footer.
