I have been thinking about it and I think one file in data/global/
similar to pg_pwd will work.  It will contain "groupname<tab>username"
and can be read in with a limited amount of code and dumped out like we
do pg_pwd.  It will basically expand to the comma-separated list of
users in the current code.

We can mark group names with "+", e.g. +staff.
