(collation) Building postgresql on FreeBSD, the pros and cons of icu

[Patrick Dung <patrick_dkt@xxxxxxxxxxxx>]

Hi all,

By default, FreeBSD ports does not build postgresql with icu (http://www.icu-project.org/).

Some questions:

1) It is necessary that icu should be used on FreeBSD?
I have heard that FreeBSD's locale (glibc) has sorting problem with Postgresql UTF8 DB.

reference: http://wiki.postgresql.org/wiki/Todo:ICU

2) After searching in google, it was said that using ICU is faster (in terms of sorting in locale).

3) Any other pros and cons?

Thanks,

Patrick
