Yeah, that does look like a corrupted-data problem.  If you wanted to
rebuild with debugging symbols turned on, it might be possible to
extract the location of the bad tuple directly from the corefile.
Short of that, what I'd do is find out what query the backend is
crashing on (turn on debug query logging), and then investigate the
tables involved using queries like "select ctid,* from foo limit N".
By varying the limit you can home in on just where the bad tuple is.
