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.
