Dear list

as you know there was a  discussion in list about
using nls_string or nls_strxfrm function for having
multiple locale at the same time in postgresql.

many of developers accepted this method as a correct
but not perfect solution.

the main problem of this function is using setlocale
and its bad performance.

I attached this mail one implementation of strxfrm
functions (prepared by karl zak)

would you please add this function to the contribution
so that other people can use this function and do some
improvment in it?


Best Regards
