Yes, it's OK for 2.x series.

For JSON, please take a look at how MongoDB presents its output.

For SQL, PostgreSQL or MySQL or CockroachDB would be nice -they
even colorize table headings. In any case, SQL demands tabular
form. Tabular output is difficult. Especially with non-ascii
characters and alphabets, which have digraphs,
and ligatures.
