This is how we did it, when there was a special requirement to do so for a special occasion,
make a new user (lets call it "readonly") and have the app authenticating with this user.
Manage his privileges with smth like: (for every table)
CREATE user readonly;
REVOKE ALL ON DATABASE <your database> FROM readonly;
(for each table) GRANT SELECT ON <your table> TO readonly;

For this last one you might need to write a script, producing the sql commands.
