The command is: psql $db_url -c "copy (select row_to_json(x_tmp_uniq) from public.mytable x_tmp_uniq) to stdout"
postgres version: 14.7
Does this mean COPY and java CopyManager may not help since my psql command already uses copy?
Regarding pg_dump, it does not support json format which means extra work is needed to convert the supported format to jsonl (or parquet) so that they can be imported into snowflake. Still exploring but want to call it out early. Maybe 'custom' format can be parquet?
Thanks
