Foreign tables add an extra "wholerow" ROWID_VAR to the HypertableModify scan's targetlist. It causes adjust_appendrel_attrs() to assert when the Var has been previously modified by ts_replace_rowid_vars(). This patch keeps the original unaltered targetlist letting adjust_appendrel_attrs() properly replace these ROWID_VARs for the chunks.
