If I run Dan Wood's test case again, the obvious symptom (spurious
duplicates) goes away. However, the enhanced amcheck, and thus CREATE
INDEX/REINDEX, still isn't happy about this:
postgres=# select bt_index_check('t_pkey', true);
DEBUG: 00000: verifying presence of required tuples in index "t_pkey"
LOCATION: bt_check_every_level, verify_nbtree.c:424
ERROR: XX000: failed to find parent tuple for heap-only tuple at
(0,6) in table "t"
