#***********************************************************************
#
# 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.
