Removing pg_standby has been proposed a couple of times in the past. See
https://www.postgresql.org/message-id/20170913064824.rqflkadxwpboabgw@alap3.anarazel.de
for the latest attempt.
Masao-san, back in 2014 you mentioned "fast failover" as a feature that
was missing from the built-in standby mode
(https://www.postgresql.org/message-id/CAHGQGwEE_8vvpQk0ex6Qa_aXt-OSJ7OdZjX4uM_FtqKfxq5SbQ%40mail.gmail.com).
I think that's been implemented since, with the recovery_target
settings. Would you agree?
I'm pretty sure we can remove pg_standby by now. But if there's
something crucial missing from the built-in facilities, we need to talk
about implementing them.
