Subject: [PATCH v1] docs: Link to the correct protocol version inspection
 function

The docs for max_protocol_version suggested PQprotocolVersion instead of
PQfullProtocolVersion to find out the exact protocol version. Since
PQprotocolVersion only returns the major protocol version that is bad
advice.
