I noticed recently that permissions checking is done differently for the server certificate key than the client key. Specifically, on the server the key can have 640 perms if it is owned by root.

On the server side this change was made in 9a83564c and I think the same rational applies equally well to the client key. At the time managed keys on the client may not have been common but they are now.

Attached is a patch to make this change.

I was able to this this manually by hacking 001_ssltests.pl like so:

-    chmod 0640, "ssl/${key}_tmp.key"
+    chmod 0600, "ssl/${key}_tmp.key"
        or die "failed to change permissions on ssl/${key}_tmp.key: $!";
-    system_or_bail("sudo chown root ssl/${key}_tmp.key");

But this is clearly not going to work for general purpose testing. The server keys also not tested for root ownership so perhaps we do not need that here either.

I looked at trying to make this code common between the server and client but due to the differences in error reporting it seemed like more trouble than it was worth.

Added to next CF: https://commitfest.postgresql.org/35/3379
