PostgreSQL 12 - psql - csv output

After some years and long discussion, a psql console has great feature - csv output (implemented by Daniel Vérité).

Usage is very simple, just use --csv option.

[pavel@nemesis postgresql.master]$ psql --csv -c "select * from pg_namespace limit 10" postgres
oid,nspname,nspowner,nspacl
