Hi,

It depends on what you want to achieve with using packages.

If you just want to group a number of functions and procedures, just
create a schema for it (schemas are totally unrelated to users in
PostgreSQL), e. g.
CREATE SCHEMA functions;
and then
CREATE FUNCTION functions.f1 (integer) RETURNS integer LANGUAGE plgpsql
AS $$
...
$$;

Unfortunately, there are no schema related variables. You will have to
resort to saving values in some (temporary, unlogged, normal) table.

There is another way of using a setting as a variable described here:

Regards,

Holger
