Why are why you using back-ticks for sqlite identifiers instead of double quotes?

[SpyrosRoum]

If you switch to double quotes then you avoid this sqlx issue, which would allow RETURNING to work for SQLite for every backend (plus you are more correct according to the SQL standard))
SQLite keywords

It might not be a problem with SQLx. May be we can cross-check using Rusqlite?
Anyhow I support this change.

[SpyrosRoum]

So I run most of what's in the tests in table.rs, I checked returning and I checked a few select queries as well.
All of them seem to work fine with double quotes

With this closed, the comments saying that RETURNING doesn't work for sqlx can be removed now.
I didn't think it was fitting to include the change in the pr but I'm happy to open a new one if you want

@billy1624 I think you might want to close the SQLx issue
