If your goal is "allow any local user who is a member of group X
to connect", you might be able to do it by setting restrictive
filesystem privileges on the postmaster's Unix-socket file. This
has some disadvantages --- notably, there's no way to override and
let selected non-group-members in too --- but it's worth considering.
See the unix_socket_group and unix_socket_permissions GUCs.
