v37- would have handled this as the list of PQ parameters was dynamically generated and only those parameters reported by the specific version of the server showed up in \conninfo+. Of course that may have led to confusion in which some versions show role while others did not, but that could be dealt with in documentation. -- Sami Imseih Amazon Web Services (AWS)
