Thank you, I've enabled logging, but couldn't see anything suspicious there. Also the 60%-120% CPU-eating postmaster processes are now suddenly gone. I suspect this is some bug in the postgresql-server-8.1.21-1.el5_5.1 delivered with CenOS 5.5/64 bit, because I don't have many simultaneous users ( < 100) and not that many queries. I'll try to upgrade to 8.4.4 as described at http://www.pgrpms.org/ later. I'm a bit confused though that they do not support "yum update" anymore (I think that worked earlier with PGDG....)
