Write instructions on how to do this in any IDE.

In PyCharm: Move cursor on any occurence or definition of "database" fixture, press the "Rename" hotkey (Shift+F6), delete old name and type new name, press Enter key to confirm.

Wouldn’t that be limited to the single function?

A single fixture, yes. If there are many fixtures of the same name in different test modules, it wouldn't work, but that's not how I understood the problem in the blog post, which says

>rename every instance of a pytest fixture from database -> db

Every instance of a fixture, not every instance of all fixtures of the same name.

The fine folks at JetBrains already have done just that:

I don’t think that this will handle what the author wants, though. If each function takes db as an argument and uses it internally, those don’t count as references that you can change globally, right?
