Thanks Robert. After applying all the 5 patches (v8-00*) against PG
v13 (commit id -afb5465e0cfce7637066eaaaeecab30b0f23fbe3) ,
There is a scenario where pg_validatebackup is not throwing an error if
some file deleted from pg_wal/ folder and but later at the time of
restoring - we are getting an error
[centos@tushar-ldap-docker bin]$ ./pg_basebackup -D test1

backup, touch
"/home/centos/pg13_bk_mani/edb/edbpsql/bin/test1/recovery.signal" and
add required recovery options.
If you are not restoring from a backup, try removing the file

Be careful: removing
"/home/centos/pg13_bk_mani/edb/edbpsql/bin/test1/backup_label" will
result in a corrupt cluster if restoring from a backup.
