-----------------------------------
Summary: [Rust][DataFusion] Implement optional second argument to
ltrim and rtrim functions
Key: ARROW-11164
URL: https://issues.apache.org/jira/browse/ARROW-11164
Project: Apache Arrow
Issue Type: Improvement
Components: Rust - DataFusion
Reporter: Andrew Lamb
Attachments: 103891510-f84d8800-50b7-11eb-929e-94f56c2364cd.png
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.
