The array containment operators now behave per mathematical expectation for empty arrays (ie, an empty array is contained in anything). Both these operators and the query_int operators now work as expected in GiST and GIN index searches, rather than having corner cases where the index searches gave different answers. Also, fix unexpected failures where the operators would claim that an array contained nulls, when in fact there was no longer any null present (similar to bug #5784). The restriction to not have nulls is still there, as removing it would take a lot of added code complexity and probably slow things down significantly. Also, remove the arbitrary restriction to 1-D arrays; unlike the other restriction, this was buying us nothing performance-wise. Assorted cosmetic improvements and marginal performance improvements, too. |
