Since an index header page has to point to at least 2 other leaf or
header pages, it stores at least 2 keys per page.
I would alter the todo to say:
* fix btree to give a useful elog when key > 1/2 (page - overhead) and not
abort

A key of more than 4k will want a more efficient index type than btree
for such data anyway.
