I have some comments on this patch.

I'm +1 for always output all results without having knobs.

Documentation (psql-ref.sgml) has another place that needs the
same amendment.

Looking the output for -t, -0, -A or something like, we might need
to introduce result-set separator.

# -eH looks broken for me but it would be another issue.

Valid setting of FETCH_COUNT disables this feature. I think it is
unwanted behavior.

regards.
