### Tell us about what you're trying to solve. What challenges are you facing?

When using the `heroku pg:bloat` CLI command the output is a fixed width. Index names are often autogenerated by an ORM and quite long so they get cut off. This makes the bloat command useless to me because I can't tell the difference between half of the indexes listed.

I would like the output width to match the width of the user's terminal.
