Yes, this is a critical error.
Unless my math is off, a PostgreSQL disk file should not contain more
than 131072 blocks (1GB / 8KB), so something is whacky there.
But I find the second entry just as alarming.
I am no hardware guy, but I believe that a bus error would indicate a
hardware problem.
Is there a chance that you can perform a thorough hardware check
on the machine?
Make sure that you have a good backup from before this happened.
