Please see the attached patch with the comments.
Changes in the patch:
A client-side PGREDIRECTLIMIT parameter has been introduced to control
the maximum number of retries.
BE_v3.1 sends a ProtocolNegotiation message. FE_v3.1 downgrades to v3.0
upon receipt of this message.
FE falls back to v3.0 if 3.1 is not supported by the server.
>> I hadn't really thought deeply about whether redirection should
happen before or after authentication. For the most part, before seems better,
because it seems a bit silly to force people to authenticate just so that you
can tell them to go someplace else. Also, that would lead to double
authentication, which might for example result in multiple password
prompts, which users might either dislike or find confusing.
Yes, redirection before authentication would avoid multiple password
prompts.
