I think you have to change the data or change the behavior of your application . The usual solution to this sort of thing is to provide a functional index on the problem field that computes a "simplified" version of the text - stripping accents, dumbing all dashes down to simple minus signs, etc. I'm not aware of any canned tool to do this in PostgreSQL. Everyone's needs seem to vary, so it'd be hard to provide one. -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
