<p>There is legitimate reason to reject this on the basis of nondeterminism.<p>While we are surely obliged to "hold our
noses"and support "SELECT *", as:<br /> A) The SQL standard obliges us, and<br /> B) People already use it a
lot,<p>Neitherof those factors hold true for the EXCLUDING notion. So all things are decidedly not equal.<p>By all
meansI find it an interesting feature, but that shouldn't be mistaken for necessarily being a desirable feature. <p> I
don'tthink I wish it. We're telling our developers not to use "select *", and I don't think having "select * except "
wouldchange that policy, beyond requiring us to waste time explaining :<p>"No, we're not changing policy. The fact
thatPGDG added this to 9.2 does *not* imply our policy was wrong."
