Actually, there's another issue, which is where to send the prompt. If we're using /dev/tty the answer is clear, but if we're proposing to read from stdin then it's not necessarily the case that stdout (or even stderr) is appropriate. Arguably a prompt is useless except to a human user, so maybe the rule is "if stdin is a tty according to pset.notty, then prompt to /dev/tty; otherwise suppress the prompt altogether". Or we could prompt to stderr instead of /dev/tty in this case. I'm not sure if there are plausible use-cases where stdin leads to the terminal and stderr doesn't. Surely there are precedents for this sort of thing in existing programs; can anyone point to any programs that seem to get it right (or wrong)? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
