Review comment:
I'm following `psql` convention. Deviation from that is okay but would
be a thoughtful decision.
So far `psql` is a bit messy because you can have `csv`, `aligned` which is
table, `unaligned` which is `|` separated values. In an ideal world we should
strive for `csv`, `table`, `json`, `row-json` which is basically transposed
json, and some more. WDYT?
