These messages were lost in commit 05fd30c0e7. Put them back. This makes one change in the error message behavior compared to v16, in the case that the server responds to GSSRequest with an error instead of rejecting it with 'N'. Previously, libpq would hide the error that the server sent, assuming that you got the error because the server is an old pre-v12 version that doesn't understand the GSSRequest message. A v11 server sends a "FATAL: unsupported frontend protocol 1234.5680: server supports 2.0 to 3.0" error if you try to connect to it with GSS. That was a reasonable assumption when the feature was introduced, but v12 was released a long time ago and I don't think it's the most probable cause anymore. The attached patch changes things so that libpq prints the error message that the server sent in that case, making the "server responds with error to GSSRequest" case behave the same as the "server responds with error to SSLRequest" case.
