Ah of course. I now remember why I thought of this. I wrote a simple c
program to access my postgreSQL database and when I updated, the c

Don't forget to check that your /etc/apt/sources.lst entries point to
etch and not testing, otherwise you may end up with a broken system once
etch goes stable.
