PostgreSQL , recovery.conf , postgresql.conf
背景
PostgreSQL 12版本以前，配置PostgreSQL数据库恢复、流复制STANDBY，都需要配置recovery.conf，如果要修改配置，需要重启数据库。
从PostgreSQL 12开始，recovery.conf的配置文件将去掉，原有的配置内容，将整合到postgresql.conf中。并且有些配置的修改支持reload，不需要重启生效。

Integrate recovery.conf into postgresql.conf
recovery.conf settings are now set in postgresql.conf (or other GUC
sources). Currently, all the affected settings are PGC_POSTMASTER;
this could be refined in the future case by case.
Recovery is now initiated by a file recovery.signal. Standby mode is
initiated by a file standby.signal. The standby_mode setting is
gone. If a recovery.conf file is found, an error is issued.
The trigger_file setting has been renamed to promote_trigger_file as
part of the move.
The documentation chapter "Recovery Configuration" has been integrated
into "Server Configuration".
pg_basebackup -R now appends settings to postgresql.auto.conf and
creates a standby.signal file.
