You can put in a some triggers that do a few things, and I think a rule
on SELECT will round it off.
on Insert: populate a column with CURRENT_USER
on Update and Delete: refuse unless CURRENT_USER matches the column
on SELECT rules, apply a filter that column = CURRENT_USER
You also may put in an override for all three that if the CURRENT_USER
is in some particular group these filters will not apply. One level
might be just for selects, a higher level for updates/deletes.
Or you can do the reverse, and say that these filters only apply if the
user is in a certain group.
