I'd recommend
pg_filedump -f -i -R <blocknum> <filename>
where <blocknum> is whatever page you need to look at (the high part of
the TIDs of the bad tuples), and <filename> is going to be of the form
$PGDATA/base/<dbnum>/<filenum>
You get the DB number from
select oid from pg_database where datname = 'yourdbname';
and the file number from
select relfilenode from pg_class where relname = 'yourtablename';
