> https://github.com/apache/arrow/pull/9108 adds the ltrim and rtrim functions to datafusion, following postgres. However, postgres offers a second optional argument (the character to trim) that is not yet implemented, as described on https://www.postgresql.org/docs/9.1/functions-string.html
> For example:

> This ticket tracks the work to add support for the second optional arguments (what character to trim) - it would probably be a good introductory item for new contributors.
> There is more context here:
