Function create_stmt_rename_refs

pub fn create_stmt_rename_refs(
    create_stmt: &mut Statement<Raw>,
    from_name: FullItemName,
    to_item_name: String,
) -> Result<(), String>

Updates all references of from_name in create_stmt to to_name or errors if request is ambiguous.

Requests are considered ambiguous if create_stmt is a Statement::CreateView, and any of the following apply to its query:

• to_name.item is used as an Ident in query.
• from_name.item does not unambiguously refer to an item in the query, e.g. it is also used as a schema, or not all references to the item are sufficiently qualified.
• to_name.item does not unambiguously refer to an item in the query after the rename. Right now, given the first condition, this is just a coherence check, but will be more meaningful once the first restriction is lifted.
