Nobody else has reported any such thing. We do have a lot of PG
developers (including me) who use macOS regularly, so if there were a
generic problem of this sort I'm pretty sure we'd have heard about it.
In any case, we can't really investigate something we can't reproduce.
I suppose your problem is with the client side, since the PG server
wouldn't normally be involved in echoing individual characters.
If you're using pgAdmin, there's a separate bug reporting process
for that (this list is just about bugs in the core PG software).
