Yes, it does need an equal sign. That was a type-o that I just didn't
see. Fixed and re-ran. Still doesn't work.

Yes, This says "All but ADH and low." I changed this line to just be
ssl_ciphers = 'ALL' . Stopped, started, and re-ran and it still
doesn't connect. The messages in the log file say "cipher or hash
unavailable". Since the files of the ciphers are definitely on the
system, this suggests that either postgres doesn't know where to find
them or the permission on them are wrong.

The default is
#ssl_ciphers = 'ALL:!ADH:!LOW:!EXP:!MD5:@STRENGTH' # allowed SSL
ciphers

It needs a cipher or a hash. I don't know what it might use as a
hash. I found the cipher files. Unfortunately, I have two sets
because I have two versions of OpenSSL running. This might be part
of my problem, but I don't want to take a chance on messing up what's
already running. I don't know how to tell postgres which set of
cipher files to use. It's in the OpenSSL path, but not the complete
path.
