Hi,

Sorry for the delay.

I also think so.

I'd like to avoid adding new parameter for warm-standby
if possible because currently the setup of it is already
complicated. But, I don't have another good idea yet other
than the already proposed. Sorry.

Personally, I'd rather make pg_standby delete a trigger file
when the timeline history file is requested even if this would
break the current behavior, than the setup of warm-standby
becomes more complicated.
