Be advised that I'm going to be on the warpath again in the morning.
I observe that the substantial amount of care we have taken over
XLogFlush's handling of bad-input-LSN scenarios has been completely
destroyed by the UpdateMinRecoveryPoint patch, which will fail
disastrously (leaving the database unstartable/unrecoverable) if a
bogusly large LSN is encountered during recovery.
However, I grow weary...
