Why not use function which returns table and wrap the
logging (auditing) code in it ?
Because to use a trigger function, you need a trigger, and as previously
stated, you cannot have a trigger on select. The same applies for a rule.

Melvin: The proposal is to do something of the form
SELECT * FROM selecting_function()
And have selecting_function() perform any necessary auditing.
I guess this work fairly well - as long as you remember to remove SELECT
privileges on the wrapped table from everyone and setup

Dave and Dmitriy,
I know a function can be used, but the point is to log a table whenever
someone else does a SELECT on it.
It cannot be depended on that a user will include that (or any specific
function in a SELECT. iow, when any user does SELECT ... FROM tablex; then
logging should occur.

Q: How can I send tuple id (integer primary key) via notify using Rule?
You can't --- NOTIFY doesn't take variables in its parameters.
(That's a general property of utility commands, not just NOTIFY.)
Use the pg_notify() function, instead.

I don't know if you can quite write the generalized notification function you
