Hi,

When doing a PITR style recovery, with recovery target set, we're
currently not doing a fast promotion, in contrast to the handling when
doing a pg_ctl or trigger file based promotion. That can prolong making
the server available for writes.

I can't really see a reason for this?

Greetings,

Andres Freund
