Description

MySQL and Postgres support the \G modifier at the end of a query to present output in a vertical format instead of a horizontal one. It's supremely useful when you have a lot of columns. We should adopt the same.

Research direction
Review the ksql CLI output rendering code, likely in the ksql cli module. Identify where query results are formatted horizontally. Implement support for a vertical output mode, either via a modifier like '\G' or a flag. Reference MySQL's implementation for guidance.
