Yea, it's possible.

Write functions to access to the table (for select, for insert and so
on) as superuser, with secutity definer, revoke all rights from the
user.

Users can only access to the table with the functions, within this
functions check if the current_user has rights for the record.

There are some examples how to do that, please use google ;-)
