99.999% of the time, if you put SELECT * into code, you should be strung
up by your own entrails. But do you mean to tell me that when you're
testing stuff on the command line you never, ever use SELECT *?
BTW, de-coupling column definition and presentation order from internal
column order in the tuples is mandatory before PGSQL could store things
internally in the most optimal order. I find it very interesting that
many people assumed that PGSQL ordered columns however it wanted in the
tuples; I don't know of any major database that does this, even though
it probably makes a lot of sense (of course some DBA's would be very
unhappy about the loss of control, so you'd probably want an over-ride).
