Disable tests involving ZLIB on Windows for pg_receivewal
As reported by buildfarm member bowerbird, those tests are unstable onWindows. The failure produced there points to a problem with gzflush(),that fails to sync a file freshly-opened, with a gzFile properlyopened. While testing this myself with MSVC, I bumped into a differenterror where a file could simply not be opened, so this makes me ratherdoubtful that testing this area on Windows is a good idea if thisfinishes with random concurrency failures. This requires moreinvestigation, and keeping this buildfarm member red is not a good thingin the long-term, so for now this just disables this set of tests onWindows.Discussion:https://postgr.es/m/YPDLz2x3o1aX2wRh@paquier.xyz
