Yes:
/*
* Complain if we did not roll forward far enough to render the backup
* dump consistent.
*/
if (XLByteLT(EndOfLog, recoveryMinXlogOffset))
{
if (needNewTimeLine) /* stopped because of stop request */
ereport(FATAL,
(errmsg("requested recovery stop point is before end time
of backup dump")));
else
/* ran off end of WAL */
ereport(FATAL,
(errmsg("WAL ends before end time of backup dump")));
}
