Yes, that was wat I was babbling about wrt "syncing".

A reboot solved my problems -- while examining this phenomenon PostgreSQL
came to a halt and wouldn't restart due to a lack of available shared memory,
although ipcs(1) didn't show any active handles. Since I needed the database
server, I had to reboot.

I suspect something hardwarish though, I've never seen this kind of weird
behaviour before.
