Found one WAL related bug:

postgres=# CREATE TABLE test (i int);
CREATE TABLE
postgres=# INSERT INTO test SELECT a FROM generate_series(1,10) a;
INSERT 0 10
postgres=# CREATE INDEX mdx ON test USING bitmap(i);
CREATE INDEX
postgres=# INSERT INTO test VALUES (11);
INSERT 0 1
postgres=# \q

killall -9 postgres, and restart. Redo fails with:

PANIC:  bm_insert_redo: LOV item is not inserted in pos 2(requested 12)
CONTEXT:  xlog redo insert a new LOV item: rel 1663/10817/16388

I haven't dug deeper yet.
