Description
Now with #234 that make PostgresNode::port read-only is not possible to run PostgresNode::psql in a different port. We did this trick here in order to do some sanity checks after execute pg_upgrade to compare psql outputs but we should guarantee to use the same psql version (newest) over the new and old cluster to make sure the test output will be the same (psql output can change over major postgres versions).
Are there a workaround for it?
