Description:

One of the variations of ipv6 addresses is link-local addresses. It would be
nice if they could be stored in an inet column.

Example: fe80::249a:57ff:fed6:695f%host0/128 . Note the %host0

This has been discussed in the past.  One problem is that there is no
cross-platform standardization of what the name following % can be.
So we couldn't do much better than accepting it on faith and storing
it as a string, which is not very nice.  It's also very unclear how
such a marker should affect the semantics of inet operators and
functions.

Maybe someday somebody will get motivated to try to surmount those
problems, but don't hold your breath.
