And also - does PERFORM works with FOUND?

Not sure what you mean - can you elaborate?

No, perform (and execute) doesn't populate 'found' variable:
http://www.postgresql.org/docs/9.0/static/plpgsql-statements.html#PLPGSQL-STATEMENTS-DIAGNOSTICS

You have to use something like this:
get diagnostics rr = row_count;

Yes, PERFORM does populate FOUND.

From the documentation you just linked to....

  • A PERFORM statement sets FOUND true if it produces (and discards) one or more rows, false if no row is produced.
