Hi all,

Just upgraded PostgreSQL yesterday, from 8.4.5 to 9.0.1 on Debian.
This is not to start a flame on linux distributions but instead I just
want to stand out that the hard work done over the years by Martin
Pitt on the excellent PostgreSQL debian packages isn't sufficiently
appreciated.

Regards,

diego
