IIRC, I had that happen on a botched upgrade of postgres. Even if I did
a reinstall it wasn't enough. Under Debian I had to try upgrading again,
then do a "complete uninstall" (or something similar), then a fresh
reinstall and it finally worked again. It happened a couple of times and
I never figured out why. Hasn't happened lately though.
