@ktmud in reference to your comment on #9427 , I'll add the rename change here.

[villebro]

@ktmud The change will require a slightly bigger refactor. I'll do this as a separate PR later to keep this PR simple. In the meantime you can do the select and rename by applying two consecutive selects; first renaming, next selecting. This will only cause negligible overhead, hence it might even be a better idea to split out all operations from select into separate operations to keep things simple: select_columns, drop_columns and rename_columns.

LGTM, just a couple of non blocking comments

[dpgaspar]

Actually, the test def name should be changed

[villebro]

Thanks for the valuable comments @dpgaspar !
