Hi,
Another observation , if i change the ownership of a file which is under
global/ directory
i.e
[root@tushar-ldap-docker global]# chown enterprisedb 2396
and run the pg_validatebackup command, i am getting this message -
[centos@tushar-ldap-docker bin]$ ./pg_validatebackup gggg
pg_validatebackup: * manifest_checksum =

I am getting the error message but along with "*** Error in
`./pg_validatebackup': double free or corruption (!prev):
0x0000000001850ba0 ***" messages
Is this expected ?

Thanks Robert. After applying all the 5 patches (v8-00*) against PG

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
