- Copy the query into a .sql file locally.
- Remove all newlines, because psql’s
\copy command does not accept multiline arguments.
- Surround the query with parens and the
\copy command, like so: \copy (select ...) TO dump.csv CSV DELIMITER ',' HEADERS

as aliases for any column names that are the same across tables, because this method will not be as smart as Dataclips about distinguishing the column headers for those.
- pipe it to psql:
cat jeans.sql | heroku pg:psql dbcolor -a yourapp
