Were you repeatedly trying to create new databases at that time, but ran out of disk space and PostgreSQL was panicing? That would explain the issue. You can safely remove old database directories that are not referenced in pg_database - you don't even need to shut down first, as PostgreSQL doesn't know about the files anymore. Christoph
