Hello, It's not really about subject - sorry. I tryed implement support of XML. For it I need functions which know names of params.
example: create table foo(a integer); select xmlnode(a) from foo; -> <a>10</a> .... select xmlnode(a as b) from foo; -> <b>10</b> ... I have particular solution, but maybe is better general support for it. There is some ideas about functions with variable count of params?
