Hi all,
timeline.h quotes that the end point of timeline history entry means
infinity when its value is 0. But that's not completely true, I think
that what is meant here is InvalidXLogRecPtr:
{
TimeLineID tli;
XLogRecPtr begin; /* inclusive */
- XLogRecPtr end; /* exclusive, 0 means
infinity */
+ XLogRecPtr end; /* exclusive,
InvalidXLogRecPtr means
+ * infinity */
} TimeLineHistoryEntry;
And the code leads into this direction as well.
Regards,
