Hello.
I try setup replica from instructions located at https://wiki.postgresql.org/wiki/Streaming_Replication
I copied data to slave, after psql -c "SELECT pg_start_backup('label', true)" and start slave - i see in logs many message like
cp: cannot stat '/var/lib/postgresql/9.6/main/archive/000000010000000000000012': No such file or directory
