Very bizarre.  Looks like the last page it read was block 104
(851968/8192) in file "/source/data/cert/base/16556/17063".  Could you
provide a formatted dump of that page?  I'm partial to pg_filedump which
you can get from http://sources.redhat.com/rhdb/tools.html.  Use
switches -f -i to get a reasonably complete dump.
