I tried it with pg_ctl.c attached to an earlier mail today, i.e. delete all privs with
CreateRestrictedToken(DISABLE_ALL_PRIVILEGE)and enable Lock Pages in Memory with AdjustTokenPrivileges().  But it
didn'twork; AdjustTokenPrivileges() failed to enable the priv.  It's probably that CreateRestrictedToken() deletes
(unassigns?)the privs from the access token, so subsequent AdjustTokenPrivileges() can no longer enable the priv.
