<para>
Move recovery.conf settings into postgresql.conf (Fujii Masao, Simon Riggs, Abhijit Menon-Sen, Sergei Kornilov)
</para>
<para>
recovery.conf is no longer used, and recovery.signal and standby.signal are used to switch into non-primary mode.
trigger_file has been renamed to promote_trigger_file. The standby_mode setting has been removed.
</para>
------------------------------
In addition to these, I think it would be better to warn that if
there's a file named "recovery.conf" on stabdby node, postmaster won't
start up:
21909 2019-05-09 07:55:55 JST FATAL: using recovery command file "recovery.conf" is not supported
21907 2019-05-09 07:55:55 JST LOG: startup process (PID 21909) exited with exit code 1
21907 2019-05-09 07:55:55 JST LOG: aborting startup due to startup process failure
