GSSAPI. Until we support it, I think we need to tell frontend that<br>
Pgpool-II does not support GSSAPI when frontend requests it. Otherwise<br>
frontend will have a confusing message from Pgpool-II.<br>

<br>
Attached patch should do it. I don't have GSSAPI enabled frontend and<br>
I cannot test it. I would appreciate if someone tests it out.<br>
