Fix some issues that prevent this file to be processed by scripts.

While at it, mark a couple of items completed in 8.4:
!   o -Prevent long-lived temporary tables from causing frozen-xid
      advancement starvation

! * -Improve performance of shared invalidation queue for multiple CPUs

Also remove a couple of obsolete assignments.
