The row-level database ACL which I submitted yesterdat does not allow
to assign ACLs to tuples within system catalogs (like pg_database),
because it is unclear who should be the owner of tuples.

As I noted at the previous message, it considers the owner of the table
as the owner of the tuples due to several reasons. However, some of system
catalogs have its owner field like "pg_proc.proowner".
This limitation is not a fundamental one, so we can remove it soon.

But, who should be the owner of tuples within system catalogs which have
some kind of "owner" field.
