I tried the patch with openssl 0.9.8x, and got this failure at server start: FATAL: ssl_min_protocol_version setting TLSv1.2 not supported by this build Maybe it'd be worth extending that to show the max supported version, with some rats-nest of #ifdefs, but I'm not sure if it's worth the trouble. regards, tom lane
