I would further like to move all of postgresql.conf into the database, as much as possible, as well as pg_ident.conf and pg_hba.conf. Variables like current_user have a sort of nesting context functionality: calling a SECURITY DEFINER function "pushes" a new value onto current_user, then when the function returns the new value of current_user is "popped" and the previous value restored. It might be nice to be able to generalize this. Questions that then arise: - can one see up the stack?- are there permissions issues with seeing up the stack? I recently posted proposing a feature such that SECURITY DEFINER functions could observe the _caller_'s current_user.
