PostgreSQL version: 16.4
Operating system:   Ubuntu 20.04.5 LTS
Description:

Standby cluster does not start after building from Primary cluster. 

The copy2slave16.sh script was used for the building Standby cluster:
#!/bin/bash
. /home/postgres/pg.sh
LD_LIBRARY_PATH=$PGLIB $PGBIN/psql -Upgadmin -d postgres -f
/home/postgres/copy2slave16.sql > /home/postgres/copy.log 2>
/home/postgres/copy.err

copy2slave16.sql:
SELECT pg_backup_start(label => 'label', fast => true);
\! rsync -a /opt/pgdata-16/ <Standby_cluster_IP>:/opt/pgdata-16/ --exclude
postmaster.pid  --exclude pg_wal/  --exclude pg_replslot/ >
/home/postgres/rsync.log 2> /home/postgres/rsync.err
SELECT * FROM pg_backup_stop(wait_for_archive => true);

There was also an attempt to building the Standby cluster using
pg_basebackup.
Problem was a same.
