The problem only occurs if libpq thinks it might be able to do GSSAPI, but the server does not. Without the patch I proposed or something like it, this case fails to connect at all; with it, there will be an extra round-trip. Explicitly disabling GSSAPI encryption in the connection string or environment avoids the issue. The exact condition for libpq seems to be a successful call to gss_acquire_cred, but I'm not familiar with GSS in general. -- Andrew (irc:RhodiumToad)
