13: # This file implements tests to verify that ticket [31338dca7e] has been
14: # fixed. Ticket [31338dca7e] demonstrates problems with the OR-clause
15: # optimization in joins where the WHERE clause is of the form
16: #
17: # (x AND y) OR z
18: #
19: # And the x and y subterms from from different tables of the join.
