I am configuring postgres 9.6 on Linux two node (1 master and other is slave) https://www.howtoforge.com/tutorial/how-to-install-and-configure-master-slave-replication-with-postgresql-96-on-centos-7/
did all configuration as per note above, master node is running after configuration from note,
but after slave configuration form given note when I starting slave node getting below message in logs on slave side:
< 2020-03-17 01:12:07.408 +04 > LOG: database system was interrupted while in recovery at log time 2020-03-17 00:37:30 +04

quite new with postgres and wondering if I missed something or note which I follow is missing something.
Did some google but unfortunately couldn't find anything.
