Is the collation a property of the datum, or one of the comparison? If the latter, should it be really be made a sidecar of a datum, or would it make more sense to attach it to the operation being performed? I wonder if instead of trying to pass it down multiple layers till bttextcmp and further down, it would make more sense to set a global variable somewhere in the high levels, and only have it checked in varstr_cmp. -- Álvaro Herrera <alvhe...@commandprompt.com> The PostgreSQL Company - Command Prompt, Inc.
