That looks like a hardware problem ... might want to budget for a new disk

yes, and fsck is unlikely to help, though you could try.

If you've never modified template1, you could drop template0 and re-create
it from template1. Otherwise, pg_dumpall/initdb/reload would seem to be
called for. A cautious person might want to do the latter anyway in case
there's more problems than just this one.
