Interesting.

When we HAVE_IPV6, there's code to remove stuff after a % in an address.
My bet is that what you're running was not compiled with HAVE_IPV6 and
so the code is not executed. Obviously this is invoked in
pg_stat_get_backend_client_addr().

/*
* clean_ipv6_addr --- remove any '%zone' part from an IPv6 address string
*
* XXX This should go away someday!
*
* This is a kluge needed because we don't yet support zones in stored inet
* values. Since the result of getnameinfo() might include a zone spec,
* call this to remove it anywhere we want to feed getnameinfo's output to
* network_in. Beats failing entirely.
*
* An alternative approach would be to let network_in ignore %-parts for
* itself, but that would mean we'd silently drop zone specs in user input,
* which seems not such a good idea.
