Fixed issue in psycopg2 dialect where the "multiple hosts" feature implemented for 🎫`4392`, where multiple ``host:port`` pairs could be passed in the query string as ``?host=host1:port1&host=host2:port2&host=host3:port3`` was not implemented correctly, as it did not propagate the "port" parameter appropriately. Connections that didn't use a different "port" likely worked without issue, and connections that had "port" for some of the entries may have incorrectly passed on that hostname. The format is now corrected to pass hosts/ports appropriately. As part of this change, maintained support for another multihost style that worked unintentionally, which is comma-separated ``?host=h1,h2,h3&port=p1,p2,p3``. This format is more consistent with libpq's query-string format, whereas the previous format is inspired by a different aspect of libpq's URI format but is not quite the same thing. If the two styles are mixed together, an error is raised as this is ambiguous. Fixes: #4392 Change-Id: Ic9cc0b0e6e90725e158d9efe73e042853dd1263f
