For what it's worth, permissions on persistent functions could be used to 
control access to private-to-a-role transcient/session variables, see:

https://www.mail-archive.com/pgsql-hackers@postgresql.org/msg300651.html

The good point is that the implementation on top of session variables 
would be trivial and very efficient, just prefix the variable with the 
owner id in the key-value storage. The bad point is that there is no 
full-featured GRANT on the variable itself, and it looks adhoc, somehow.
