My youngest son could clearly reason when less than 18 months old.
I observed him at about 15 months, when he went to use his radio, and it didn't work. He checked it was switched on at the radio, and the volume was set up okay. He checked it was switched on at the wall. He checked that the electrical cord was plugged into the wall, and also the radio. He stood still for about a minute, and then pushed the cord plug more firmly in the radio, and the radio started working!
This was not the sequence of events that is simple imitation. He first checked the obvious, then thought about what else could be checked.
A few months earlier I watched him over several weeks figure out all the things required for water to come out of the hose pipe. Not sure of the exact order, but gradually he realised that the hose pipe need to be connected to the tap, the nozzle had to be turned the right way, and the tap had to be on.
While he is a bright child (he is now 8 years old, and in the top maths group in his class), I am sure many other children must be able to reason things out, just that people may not have been so observant, or at least not published their findings widely enough.
For my first son when he was less than a 7 days old, I held him upright on my lap. I then said "up" lifting him up, followeed by "down" and gently lowered him After a few days, and before he was 7 days old, I noticed that he tensed his leg muscles when I said "up" and relaxed his leg muscles when I said "down".
I also did the same with my third son, with similar results.
This shows that very young children can both understand simple words, and also actively attempt to cooperate appropriately!
Never underestimate children, nor judge someone's intelligence by how well they can verbally express themselves.
I am curious, which versions of Postgres are you referring too?
I guess you are talking about the 7.x.y versions. Have you tested 8.1 for queries, I know a lot of work has gone into optimising queries and making better use of indexes.
You wrote one of the rare Slashdot articles that actually gave me a lot of useful ideas to followup - or should I complain that you got me thinking too much?
I consider 2 the oddest prime because, as you say, it is the only even one.
It is also odd in the sense that thwere is a lower limit on primes, but no higher limit!

The tides that the Moon raises on the Earth are not frictionless as continents and other land masses get in the way, plus there is some friction fron the bottom of the sea.
This means that the Earth looses rotational kinetic energy to the Moon, giving the Moon extra potential energy. Hence the Earth slows down, and the Moon moves further way from the Earth.

But L inux comes before U nix - THEREFORE Sco's Unix code must all be under the GPL! -)

You will know the anmswer is correct when you find it! Note "1" is _NOT_ a prime
I feel it is far to COMPLEX for me to follow...
