Thanks for providing valuable inputs into my concerns. In the last part you mentioned and i am quoting it here "
would limit the parts of the system that would have to be cleansed of ASCII-isms to libpq and src/bin/. But that's already a nontrivial headache I suspect." I am not clear on the ASCII-isms to libpq and src/bin/. Can you share some knowledge on those items. Are those standard directory locations ? Sorry if i am being ignorant.
Regards

The last discussion around this [1] concluded that you'd probably crash and burn due to z/OS wanting to use EBCDIC encoding. There's a lot of ASCII-related assumptions in our code, and nobody is interested in trying to get rid of them.
It's possible that you could run the server in ASCII and treat EBCDIC as a client-only encoding, which would limit the parts of the system that would have to be cleansed of ASCII-isms to libpq and src/bin/. But that's already a nontrivial headache I suspect.
