I don't see any such behavior change in psql, so I agree that this is probably something to ask about on the JDBC list. My first thought was that the output change occurs when the query transitions from custom to generic plan. However, since there are no parameters involved the backend would go for a generic plan immediately. Having said that, I seem to recall that the JDBC driver has its own notion of custom vs generic execution, so maybe the issue is around there somewhere. regards, tom lane
