shm_open() is in SUSv2 and all targeted Unix systems have it.We retain a HAVE_SHM_OPEN macro, because it's clearer to readers thansomething like !defined(WIN32).Reviewed-by: Tom Lane <tgl@sss.pgh.pa.us>Reviewed-by: Andres Freund <andres@anarazel.de>Discussion:https://postgr.es/m/CA+hUKGJ3LHeP9w5Fgzdr4G8AnEtJ=z=p6hGDEm4qYGEUX5B6fQ@mail.gmail.com
