Client library version and server version are expected to match in general. AFAIK, in the past, only very conservative statements have been made about using library versions that differ from server version, particularily if using old library to connect to new server - which seems to be your case. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
