1. IIUC the name tracker should go over it and we'd have B.C and B.C__temp__0, or am I not understanding properly? Is is a hard requirement, even before the substrait parsing? I'm not sure then why we'd accept a query like `SELECT data.a, CAST(data.a as string) from data;` 2. I think your example is a bit of a mix between my two proposals; I was thinking of making CASTs appear in the case where we still don't want duplicate col names, so something like ``` SELECT B.C, CAST(B.C as TEXT) FROM table; ``` we'd get columns "B.C" and "B.C::TEXT" -- This is an automated message from the Apache Git Service.
