Now that you say that, I seem to recall that this has been reported before. It seems odd that in today's climate the Python interpreter would not cope well with Windows-style newlines. Maybe there is some configuration issue with Python itself? > I am no longer sure whether this is a problem of Postgres or of pgAdmin. Postgres is just passing the bytes from point A to point B. You could maybe argue that it's a bad idea for pgAdmin to be using a Windows-centric notion of newline, but I doubt you'll be able to sell those guys on it. Really this seems like a robustness issue for Python. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
