FWIW, you shouldn't need to use --column-inserts mode, because even in
default COPY output, pg_dump emits column name lists in the COPY commands.
So the right things should happen when reloading into a database with
modified column order.
Haven't thought about it in great detail, but your plan sounds generally
sane otherwise.
