Improve errors related to incorrect TLI on checkpoint record replay
WAL replay would cause a hard crash if the timeline expected by a
XLOG_END_OF_RECOVERY, a XLOG_CHECKPOINT_ONLINE, or a
XLOG_CHECKPOINT_SHUTDOWN record is not the same as the timeline being
replayed, using the same error message for all three of them. This
commit changes those error messages to use different wordings, adapted
to each record type, which is useful when it comes to the debugging of
an issue in this area.
