What do you get from
    select oid, * from pg_class where relname = 'bb_master';
    select oid, * from pg_class where oid = 16896;

If either one fails to get a hit, try it again after doing
    set enable_indexscan = off;

Hard to tell.  It sounds a bit like pg_class catalog damage, but the
above experiment will tell us more.
