As superuser? Take a look at whether relations are skipped during
vacuum.

Try vacuuming pg_class, pg_index, pg_attribute manually and see if that
makes the problem go away. If it doesn't, then my guess is that it's
time to see what the hanging process is doing -- try an strace on it, or
attaching it with gdb and getting a backtrace. (I hope your binaries
have debug symbols).
