The regression test cases added in commits b2cbced9e et al depended in part on the Russian timezone offset changes of Oct 2014. While this is of no particular concern for a default Postgres build, it was possible for a build using --with-system-tzdata to fail the tests if the system tzdata database wasn't au courant. Bjorn Munch and Christoph Berg both complained about this while packaging 9.4rc1, so we probably shouldn't insist on the system tzdata being up-to-date. Instead, make an equivalent test using a zone change that occurred in Venezuela in 2007. With this patch, the regression tests should pass using any tzdata set from 2012 or later. (I can't muster much sympathy for somebody using --with-system-tzdata on a machine whose system tzdata is more than three years out-of-date.)
