David E. Wheeler napsal(a):
Attached is a new version of a patch to add a CITEXT contrib module. Changes since v2:

* Optimized citext_eq() and citext_ne() (the = and <> operators, respectively) by having them use strncmp() instead of varstr_cmp(). Per discussion.

* Added `RESTRICT` and `JOIN` clauses to the comparison operators (=, <>, <, >, <=, >=). These improve statistics estimations, increasing the liklihood that indices will be used.

I'm sorry for late response. I'm little bit busy this week. I quickly look on your latest changes and it seems to me that everything is OK. I'm going to change status to ready for commit. After discussion with Pavel Stehule I changed meaning about pgFoundry vs. contrib. Contrib is OK for me.

Maybe some native speaker should review documentation.
