Let me explain the project standards in words of one syllable: user code
should not examine the contents of node trees.  That's what pg_get_expr
is for.  There is not, never has been, and never will be any guarantee
that we won't whack those structures around in completely arbitrary ways,
as long as we do a catversion bump along with it.
