Rotating the array by 180 degrees in every dimension would give the same answer for 1-dimensional arrays and give sensible answers for higher dimensional arrays. For example: 1,2,3 == 3,2,1 [1 2 3 [9 8 7 4 5 6 == 6 5 4 7 8 9] 3 2 1] I think higher dimensionality would work, it's just a bit fiddly to draw. -- Sam http://samason.me.uk/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
