So that tells us: 1. Breaking SET (col) = (val) wasn't actually intended or noticed in the original patch; 2. The break was then defended based on an incorrect reading of the spec (as I pointed out already on -bugs, the syntax _is_ legal in the spec with only one column, for just the same reasons that VALUES (1) isn't required to be VALUES row(1); the spec adds the ROW( ) construct itself in one of the syntax rules, in a way that's easy to overlook) -- Andrew (irc:RhodiumToad)
