postgres: stats collector process

Hello

I want to see statistics about the use of my postgresql 8.3 in Ubuntu 8.04.1
(Hardy) Server. The package installed is
<http://packages.ubuntu.com/hardy/postgresql>
http://packages.ubuntu.com/hardy/postgresql

The statistic in this version of postgres are by default enabled, but I
didn't see that the process "postgres: stats collector process" as say in
<http://www.postgresql.org/docs/8.3/static/monitoring-ps.html>
http://www.postgresql.org/docs/8.3/s...toring-ps.html is running in my
server.

Thanks in advanced.
