There are actually several related "BuiltInWindowExpr" in physical-expr that need to be cleaned up as well (that are no longer related to BuiltInWindowExprs). We may also be able to remove a level of trait. |

WindowFunctionInterface (remove built in list ofBuiltInWindowFunctions) #8709 🎉!!!nth_valuebuiltIn function to User Defined Window Function #13201Rationale for this change
@buraksen and @jcsherin ported the last window function over, so now we can remove the old BuiltInWindowFunction code
This was so tempting a cleanup that I had to give it a try (and I wanted to do some coding)
