Hi,
I recently wanted several times to have slave server prepared at certain
point in time to reduce the time it takes for it to replay remaining
WALs (say I have pg_basebackup -x on busy db for example).
Currently the way to do it is to have pause_at_recovery_target true
(default) and wait until pg accepts connection and the shut it down. The
issue is that this is ugly, and also there is a chance that somebody
else connects and does bad things (tm) before my process does.
So I wrote simple patch that adds option to shut down the cluster once
recovery_target is reached. The server will still be able to continue
WAL replay if needed later or can be configured to start standalone.
