I concur. If we do this, the thing to do is have *no* alias, ie, there is no way to qualify the names of the subquery output columns. (IIRC unaliased joins already work approximately like that.) Then there's not anything to have a backward compatibility problem with. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
