Update to 8.0.0rc5. This is likely the last update for this port until it
carries the 8.0 release. The postgresql80-server port is being held up by
the 4.11 release because 80-server requires scads of changes to Mk/*.mk
which won't be committed until after 4.11 is pushed out the door. Until
4.11, -devel will act as the 80-server until such time as 80-server is
enabled. Get all that? Good.
