I would apply row level security, as already pointed out.
Then, in my Perl scripts, I will force a SET ROLE depending on the
operating system group/user. In such case, you can have still a
"generic" user to use as connection/login, then change the set of
permissions on the fly as connected. Of course, row level security
must be applied against current_role and not session_user.
I would not say this is a robust approach, but can do what you want
(assuming you don't have to change thousands of Perl scripts).

Hope it helps.
