Not all are English letters, for one µ > is not. You mean "are case sensitive" right? This is not news. The point I'm basically making is that it's not going to hurt us to restrict GUC to supporting a subset of all-possible-units that can be treated case-insensitively. We're already going to restrict the allowed character set: I can guarantee you that µ, or anything else outside 7-bit ASCII, will never be accepted. It's just not worth the trouble of dealing with multiple possible encodings. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
