Ugh ... it's troubling that you have this on several different pages;
that makes it more probable that the corruption extends beyond
pg_statistic. Anyway, the next thing to try is manually truncating the
file to zero length (while the postmaster is stopped). Check the
database OID, then it should be $PGDATA/base/DBOID/16408.

Yikes. The current release in that branch is 7.4.18, and practically
every one of those 18 updates fixed significant bugs.
