It would be easier to test and develop the various modules separately. As an example, if we develop a new AM which needs WAL facility or adding WAL capability to an existing system (say Hash Index), we can just test that module, rather than whole system. I think it can help us in narrowing down the problem, if we have facility to enable it at RMGR ID level. Having said that, I think this must have the facility to enable it for all the RMGR ID's (say ALL) and probably that should be default. -- With Regards, Amit Kapila.
