Maybe a silly idea, but we could have some shared_preload_libraries
module with a command_utility_hook that intercept table creation and
randomize the logical column order. If we also have some GUC (assert
only if needed) to switch star expansion to physical-order rather than
logical-order, we could then use the regression test as a big hammer
to see if anything breaks. That's clearly not ideal (it would
obviously need some other hacks to avoid other breakage like \d and
other things) and not 100% coverage, but it should give some
confidence in any patch completeness.
