419 | * the client to somehow see that quotas have been turned off in which | |
420 | * we can't allow that to get back until the quotaoff hits the disk. | |
421 | * So how would that happen? Also, do we need different routines for | |
422 | * quotaoff start and quotaoff end? I suspect the answer is yes but | |
423 | * to be sure, I need to look at the recovery code and see how quota off | |
424 | * recovery is handled (do we roll forward or back or do something else). | |
425 | * If we roll forwards or backwards, then we need two separate routines, | |
426 | * one that does nothing and one that stamps in the lsn that matters | |
427 | * (truly makes the quotaoff irrevocable). If we do something else, | |
428 | * then maybe we don't need two. | |
