Replication server is created using

/etc/init.d/postgresql stop
mv /var/lib/postgresql/12/main /var/lib/postgresql/12/mainold
pg_basebackup --write-recovery-conf -D /var/lib/postgresql/12/main
chmod --recursive --verbose 0700 /var/lib/postgresql/12/main
chown -Rv postgres:postgres /var/lib/postgresql/12/main
/etc/init.d/postgresql start
