> What happens when using the same function more than once? @Dandandan thanks for you comment, the engine historically fails if the alias are the same, like if you run `let sql = "SELECT COALESCE(NULL, 'test'), COALESCE(NULL, 'test')";` it will fail even now. supposingly we need a separate ticket to try to do postgres behaviuor, or add some number like `coalesce_0, coalesce_1`. I'm happy to do this if needed -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
