There are some workarounds for emulation of package variables - and I am
pressing a design of session variables that can be well used like package
variables.

Currently almost all basic functionality (related to PL/SQL) is available
in Postgres. But the migration needs lot of hard manual work.

It is analogy with Cobol systems - some applications are too ugly so more
level emulation is cheaper solution, than migration to some modern :)
