Yes, I saw that, but how does that hook into nextval/setval/currval()?
I think I see it in 6.13:
a) If <next value expression> is contained in a <schema definition>,
then the applicable privileges for the <authorization identifier> that
owns the containing schema shall include USAGE privilege on the sequence
generator identified by <sequence generator name>.
