Agreed, and done.  I found btw that "fe80::something%lo0" works
perfectly well in pg_hba.conf ... so there are parts of the code
able to handle this already.

Well, let's be clear: this is entirely the fault of the inet type not
accepting what we now know to be RFC-compliant address specifications.
So we ought to put fixing that on the TODO list.  It's not happening
for 8.3 though, let alone in existing release branches, so we'd best
put in a workaround until it's there.
