+      SNAFU: c-ares versions <= 1.10 have bug which breaks CNAME-s support
+      when IPv6 has been enabled.  (Fixed upstream.)  As a workaround,
+      c-ares <= 1.10 is used IPv4-only.  So PgBouncer will drop other backends
+      only when c-ares >1.10 (still unreleased) has been out some time...

     * Show remote_pid in SHOW CLIENTS/SERVERS.  Available for clients that
       connect over unix sockets and both tcp and unix socket server.
       In case of tcp-server, the pid is taken from cancel key.
