All tables are in the one and only schema listed in the users search path and
the three tables and the relevent columns used in the test script are:

create table groups (
id serial primary key
,name text
,principal_user_id int references anothertable(id)
,...
) without oids;

create table sections (
id serial primary key
,group_id int references groups(id)
,...
) without oids;

create table site_membership (
id serial unique
,group_id int references groups(id)
,site_id int references someothertable(id)
,primary key(site_id,group_id)
) without oids;

Hope that's enough to give you the idea of the linkages.
