Yup, failures are unrelated and addressed in #876! No worries there. |

This seems to work as expected with this code. I do need to specify the region otherwise, I get this error: |
This commit introduces a new `odbc::redshift()` function intended to help setting up connections to AWS Redshift, especially when using IAM credentials. It generally follows the pattern established with `odbc::databricks()` and `odbc::snowflake()`. Note that finding IAM credentials is outsourced to `paws.common`. Some Redshift ODBC drivers (there are a few of them) can handle AWS profiles or IAM role assumption, and I did have an earlier version of this commit that did this work manually; unfortunately the supported parameters depend not only on the driver, but also the driver version, and it quickly became a mess. So: using `paws.common` here allows us to be very driver version-agnostic, and ensures we support as wide a number of IAM setups as possible. Note that I also refectored some of automatic driver discover for Databricks and Snowflake into its own helper utility so we could use the same logic for Redshift, and fixed some grammar issues in their respective error messages. Unit tests are included. Signed-off-by: Aaron Jacobs <aaron.jacobs@rstudio.com>
