Feature: Export query result as CSV

[azthec]

Something I've noticed in my workflows is the frequent need to export data for others to visualize, although the default query result table is very readable inside a nowrap buffer, it becomes unintelligible when sent to others.

A useful feature for me would be the ability to convert query output into common plaintext formats, such as CSV, and then visualize or save it.

It would be nice to have this built as an explicit function (UI trigger) but for now you can simply wrap your query like the following and it will render the csv output into the result pane:
Copy (select * from <your query here>) To STDOUT (FORMAT CSV, HEADER, DELIMITER ',');
