Hi,
Thanks for drafting those up.
For:
* Several fixes for GENERATED columns, including an issue where it was possible
to crash or corrupt data in a table when the output of the generated column was
the exact copy of a physical column on the table.
I think it's important to include the "or if the expression called a
function which could, in certain cases, return its own input".
The reason I think that's important is because there's likely no
legitimate case for having the expression an exact copy of the column.
