Alvaro Herrera 8deb6b38dc Reinstate HEAP_XMAX_LOCK_ONLY|HEAP_KEYS_UPDATED as allowed ... Commit 866e24d47d added an assert that HEAP_XMAX_LOCK_ONLY and HEAP_KEYS_UPDATED cannot appear together, on the faulty assumption that the latter necessarily referred to an update and not a tuple lock; but that's wrong, because SELECT FOR UPDATE can use precisely that combination, as evidenced by the amcheck test case added here. Remove the Assert(), and also patch amcheck's verify_heapam.c to not complain if the combination is found. Also, out of overabundance of caution, update (across all branches) README.tuplock to be more explicit about this.
