article about new features of 9.1

Hello

I wrote a article about PostgreSQL - sorry it is in Czech (try google
translator - note: there are some sentences where translator fails)

http://www.root.cz/clanky/postgresql-9-1-aneb-stale-vpred/

or

http://www.pgsql.cz/index.php/PostgreSQL_9.1_-_aneb_st%C3%A1le_vp%C5%99ed

It was nice surprise for me - there was only really positive comments
on PostgreSQL. We have a very good reputation now and features like
writeable CTEs are very expected.

so thank you all developers that worked on PostgreSQL

Regards

Pavel Stehule
