Robert Haas 419113dfdc Retry DSM control segment creation if Windows indicates access denied. ... Otherwise, attempts to run multiple postmasters running on the same machine may fail, because Windows sometimes returns ERROR_ACCESS_DENIED rather than ERROR_ALREADY_EXISTS when there is an existing segment. Hitting this bug is much more likely because of another defect not fixed by this patch, namely that dsm_postmaster_startup() uses random() which returns the same value every time. But that's not a reason not to fix this.
