I'm reading this book https://www.interdb.jp/pg/pgsql03.html? I'm debugging pg, but I can't get the parse tree like this: https://files.slack.com/files-pri/T0FS7GCKS-F047H5R2UKH/1.png, can you give me some ways to get that? I'm using vscode to debug, the watch info doesn't interest me, it gives me nothing,https://files.slack.com/files-pri/T0FS7GCKS-F048MD5BTME/quzk_6bk0sug60__f_0wh2l.png
