AFAIK, when standby_mode = on, archive recovery pauses only at end of WAL files.
When recovery target is specified and archive recovery reaches the
target, it doesn't
pause. OTOH, when pause_at_recovery_target is set, archive recovery pauses only
at the target but not end of WAL files. Neither can cover all the usecases. So
pause_at_recovery_target was implemented.
