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.
