I do not think it's a great idea to have ALTER TABLE scribbling on
the source parsetree. That tree could be in plancache and subject
to reuse later.
Mind you, I don't say that we're perfectly clean about this elsewhere.
But there is a pretty hard expectation that the executor doesn't
modify plan trees, and I think the same rule should apply to utility
statements.
