Can you send me a raw binary dump of the page using pageinspect?
Something like the following command line recipe will do it:

$ psql -XAtc "SELECT encode(get_raw_page('pgbench_pkey',
42),'base64')" | base64 -d > dump_block_42.page

Obviously you'll need to figure out which block number the problem
page is located in before you do this, but that shouldn't be hard --
get a coredump and inspect the state from amcheck a few frames down.
