If it handles the restart-after-backend-crash scenario and correctly locks out starting a fresh postmaster (after postmaster crash) until all old backends are gone, then it's probably ready to commit for more-widespread testing. I note that sysv_shmem contains some #ifdef WIN32 and #ifdef __CYGWIN__ kluges; will it now be possible to remove those, or will the Cygwin build still be using that code? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
