Those are all the same breakage though - if truly interpreted as data

supportable and only the lines format can be used. Hence my “format 0
doesn’t work” comment for array output and we should explicitly add
format 2 where we explicitly decouple lines of output from rows of
data. That said, it would seem in practice format 0 already decouples
them and so the current choice of the brackets on their own lines is
acceptable.
I’d prefer to keep them on their own line.
WFM ¯\_(ツ)_/¯
I am merely responding with options to the many people opining on the
thread.
I also don’t know why you introduced another level of object nesting
here. That seems quite undesirable.
I didn't add anything. It is an artifact of the particular query I wrote
in the copy to statement (I did "select ss from ss" instead of "select *
from ss"), mea culpa.
This is what the latest patch, as written today, outputs:
8<----------------------
copy
(select 1, g.i from generate_series(1, 3) g(i))
to stdout (format json, force_array);
[
{"?column?":1,"i":1}
,{"?column?":1,"i":2}
,{"?column?":1,"i":3}
]
8<----------------------
