Thanks for the reply.

I think disk space shouldn't be the problem:

postgres(at)farnsworth:/usr/local/pgsql/data/pg_log$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 7.5G 4.1G 3.1G 58% /
none 496M 228K 496M 1% /dev
none 501M 140K 501M 1% /dev/shm
none 501M 100K 501M 1% /var/run
none 501M 0 501M 0% /var/lock

It is an Ubuntu 10.10 running in a VirtualBox. The storage is located
locally on my HDD, no SAN or network access.

I'm afraid it is an error in my code...
