Attempt to fix endianess issues in new hash partition test.
The tests added as part of9fdb675 yield differing resultsdepending on endianess, causing buildfarm failures. As the differencesare expected, split the hash partitioning tests into a different fileand maintain alternative output. The separate file is so the amount ofduplicated output is reduced.David produced the alternative output without a machine to test on, soit's possible this'll require a buildfarm cycle or two to get right.Author: David RowleyDiscussion:https://postgr.es/m/CAKJS1f-6f4c2Qhuipe-GY7BKmFd0FMBobRnLS7hVCoAmTszsBg@mail.gmail.com
