No. You could use a view with UNION ALL perhaps. (The subtext here is that past discussion of inheritance has generally focused on *eliminating* differences between parent and child tables, so as to make query planning and execution faster/simpler. That is, when the discussion doesn't consist of somebody wanting to get rid of inheritance altogether. I think the enthusiasm for supporting even-less-compatible child tables will be not distinguishable from zero.) regards, tom lane
