+1, but I'm inclined to make it read "... is too long". > # And the messages are missing trailing line breaks. I was about to question that, but now I remember that pg_upgrade has its own logging facility with a different idea about who provides the trailing newline than common/logging.[hc] has. Undoubtedly that's the source of this mistake. We really need to get pg_upgrade out of the business of having its own logging conventions. regards, tom lane
