protocolversion will be accepted. Is this what we wanted? Should we raise the default in libpq as well?
This was discussed [0] when the connection settings were introduced, and the
concensus was to leave them alone [1] to allow for example a new pg_dump to
work against an old server. Re-reading the thread I think the argument still
holds, but I was about to respond "yes, let's do this" before refreshing my
memory. Perhaps we should add a comment explaining this along the lines of the
attached?
