FWIW, I can confirm that HPUX 10.20's diff hasn't got it. That would not affect gaur/pademelon, if we make this change, because I installed GNU diffutils on that machine a decade or two ago. It might be a bigger issue for the other HPUX critters though. Some other data points: * POSIX 2008 requires diff -u. * SUS v2 (POSIX 1997) does not. * My other pet dinosaur, prairiedog (macOS 10.4 something), has it. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
