The good news is that that's the toast table for pg_statistic,
which means that there is exactly no irreplaceable data in it.
If all else fails, you can just truncate pg_statistic and then
re-ANALYZE the whole database to rebuild it.
(I say "just" truncate pg_statistic, but you'll have to do that
in a standalone backend started with the -O option, else there
are permissions checks that will prevent it.)
The bad news is that there might be more corruption lurking
elsewhere. What event precipitated this?
I think we have seen some bugs that would preferentially affect
pg_statistic, but not recently. If you're not running a current
minor release, an update is advisable.
