Re: Emitting JSON to file using COPY TO - Mailing list pgsql-hackers

When the source has json fields with non-significant line feeds, the COPY
output has these line feeds too, which makes the output incompatible
with rule #2 at https://jsonlines.org  ("2. Each Line is a Valid JSON
Value").

create table j(f json);

insert into j values('{"a":1,
"b":2
}');

copy j to stdout (format json);

Result:
{"f":{"a":1,
"b":2
}}

Is that expected? copy.sgml in 007 doesn't describe the output
in terms of lines so it's hard to tell from the doc.
