Oh, I get your point. But yes, I expect that in case of promotion request during a pause, the user (me too) will want
tohave exactly the current state, not latest available in WALs.
Real usercase from my experience:
The user wants to update a third-party application. In case of problems, he wants to return to the old version of the
applicationand the unchanged replica. Thus, it sets a pause on standby and performs an update. If all is ok - he will
resumereplay. In case of some problems he plans to promote standby.
But oops, standby will ignore promote signals during pause and we need get currect LSN from standby and restart it with
recovery_target_lsn= ? and recovery_target_action = promote to achieve this state.
