Mention standby.signal in FATALs for checkpoint record missing at recovery
When beginning recovery from a base backup by reading a backup_labelfile, it may be possible that no checkpoint record is availabledepending on the method used when the case backup was taken, which wouldprevent recovery from beginning. In this case, the FATAL messagesissued, initially added byc900c15, mentioned recovery.signal asan option to do recovery but not standby.signal. Let's add it as anavailable option, for clarity.Per suggestion from Bowen Shi, extracted from a larger patch by me.Author: Michael PaquierDiscussion:https://postgr.es/m/CAM_vCudkSjr7NsNKSdjwtfAm9dbzepY6beZ5DP177POKy8=2aw@mail.gmail.com
