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.
