Previously when an archive recovery or a standby was starting and reached the consistent recovery state but hot_standby was configured to off, the error message when a client connectted was "the database system is starting up", which was needless confusing and not really all that accurate either. This commit improves the connection denied error message during recovery, as follows, so that the users immediately know that their servers are configured to deny those connections. - If hot_standby is disabled, the error message "the database system is not accepting connections" and the detail message "Hot standby mode is disabled." are output when clients connect while an archive recovery or a standby is running. - If hot_standby is enabled, the error message "the database system is not yet accepting connections" and the detail message "Consistent recovery state has not been yet reached." are output when clients connect until the consistent recovery state is reached and postmaster starts accepting read only connections. This commit doesn't change the connection denied error message of "the database system is starting up" during normal server startup and crash recovery. Because it's still suitable for those situations.
