In the test run that Vince had posted to his web tool, the server process
apparently didn't have write permission to the source tree, so all the
tests that did a COPY failed, plus all subsequent tests that depended on
those tables.  Additionally, the installcheck is also prone to fail if
template1 was initialized with a different multibyte encoding, if there
was a different locale during initdb, or if there's something fishy in
postgresql.conf.  At least I wouldn't accept installcheck output as a
final result before seeing 'check'.

Additionally, make check also tests 'make install' and 'initdb'
robustness, which installcheck doesn't do, so the former should be
preferred as final test result.
