Hm, the library on F25 is also avahi's.  Digging in the archives, I find
this old thread reporting the same behavior:

https://www.postgresql.org/message-id/flat/17824.1252293423%40sss.pgh.pa.us

So now I'm wondering if you know something the rest of us don't about
how to configure the platform for bonjour to work.

I'm also a bit disturbed about the report that libdns_sd was causing
the postmaster to become multithreaded.  If still true, that's quite
bad, and might be a reason to decide we don't want this change after
all.
