No, I believe Peter has read the spec correctly. Further down they have <character translation> is a function for changing each character of a given string according to some many-to-one or one-to-one mapping between two not necessarily distinct character sets. So this is intended as a one-character-at-a-time mapping, not a language translation (which would be far beyond what anyone would expect of a database anyway). One thing that's really unclear to me is what's the difference between a <character translation> and a <form-of-use conversion>, other than that they didn't provide a syntax for defining new conversions. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
