Hi, since postgresql multidimensional arrays can't have different size per axis, I was wondering what would happen in case I used an array of, say, 10x10 elements, where only 10x2 elements are filled and the rest are NULL. I guess the NULL elements take space (and I would have 80% of the space wasted), but I'm not sure... Can someone confirm? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
