invalid page header in pg_statistic

How do I fix this 7.4.6 issue short of initdb?

invalid page header in block 110 of relation "pg_statistic"

I looked at the block via pg_filedump (included below), and it
does not appear to me to be corrupted, so not sure what I would
zero out, if anything.

TIA.
