## Which issue does this PR close? - Closes #15596 ## Rationale for this change Explained in issue. Common in other cli programs implemeting querying of data. ## What changes are included in this PR? Add a pager (`less` by default). Check that it exists. Use it for query output. Allow some manipulation of which pager program is used, and what its command line arguments are, via `\pset` (following `psql` usage of `\pset`) Allow use of pager to be switched off. Do not use a pager if stdout is redirected to a non-tty. ## Are these changes tested? Not in unit tests. ## Are there any user-facing changes? Yes. The purpose of these changes is to improve UX. Not certain if the change from specifying format using `\pset csv` to using `pset format csv` is considered a breaking change. In any case, `\pset` appears to come from `psql`, which uses subcommands to specify several areas of output configuration, one of which is `pager`. `datafusion-cli` should therefore have used `\pset format whatever` from the outset. -- This is an automated message from the Apache Git Service.
