The code that performs a cast from string to array doesn't take into account the width of the string type it is producing. This doesn't show up when the input is a literal constant because the constant is first parsed as an array of (vanilla) strings which is then subjected to a cast (to array of strings with width). Fixes cockroachdb#50132. Release note (bug fix): Fixed some cases where casting a string to a width-limited string array was not truncating the string.
