Hi,
I was able to manage upgrade testing with cluster which does not have plsh for now.
But I have another problem. All my data TB is in the tablespace in PGData directory, I did the upgrade using link method, now I got this warning.
Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade so,
once you start the new server, consider running:
analyze_new_cluster.sh
Could not create a script to delete the old cluster's data
files because user-defined tablespaces exist in the old cluster
directory. The old cluster's contents must be deleted manually.
1) Does This means , I can't delete old cluster data directory? Or I can delete it manually?
2) Deleting old data directory will effect any functionality of postgresql new cluster?
3) Also Need some clarification on link mode, what if I upgrade from 9.5. to future release using pg_upgarde link mode will still work on same data directory?
Thanks,
Yogi

I guess you failed to remove PL/sh in the original cluster.
Did you try the following in all databases:
DROP LANGUAGE plsh CASCADE;
DROP FUNCTION plsh_handler();
DROP FUNCTION plsh_validator(oid);
