In the meantime I noticed that DoCopy is subject to the same problem,
since it also uses PreparableStmt. I'll post a patch in a bit.

I tried, but couldn't find the location anywhere. None of the nodes for
ModifyTable statements have location :-( We could add one now -- while
it's a bit late for 15, we're likely going to have a catversion bump due
to the JSON revert, so it might be fine.
