Re: Postgres on IBM z/OS 2.2.0 and 2.3.0

Tom,
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.
