Broken src/test/regress/mb/* tests

broke src/test/regress/mb/* tests because the message:

"WARNING:  hash indexes are not WAL-logged and their use is discouraged"

does not emit any more in the test.  I have committed and pushed the
fix to master and 9.5 stable branches (tests in the previous stable
branches do not emit the message).

Best regards,
