I have the following related tables:
PEOPLE
--------------
peopleid pkey,
name,
etc
GROUPS
-------------
groupid pkey,
description,
etc
PEOPLEGROUPS
-------------------
peopleid pkey/fkey,
groupid pkey/fkey
What is the CORRECT way (in Postgres) to define the PEOPLEGROUPS table so
that it has both the double primary key AND still acts as a foreign key for
people.peopleid and groups.groupid? Can i specify both or is this not
necessary? Any suggestions would be appreciated.
Thanks!
