I've gotten interested again in the issue of row comparisons, eg
(a, b, c) >= (1, 2, 3)
We've discussed this before, the most comprehensive thread being
http://archives.postgresql.org/pgsql-performance/2004-07/msg00188.php
but nothing's gotten done. Unless someone's already working on this
I think I will take it up.
Can someone explain to me how:
(a, b) < (1, 2)
is different to
a < 1 and b < 2
?
