I just installed postgres on Debian 6 with apt-get. It works fine, but I had to change some configuration in postgresql.conf and now I'm trying to restart postgres.
If I try "service postgresql restart", I get the following error:
Stopping PostgreSQL 9.0 database server: mainError: Could not open /proc/8134/comm ... failed!
The same happens with cd /etc/init.d/postgresql restart
I tried this last as root and also as postgres user
