Subject: docs: Link to the correct protocol version inspection function

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.
