> A variable number number of elements can be removed from lists and sets using an update
statement of the form "update .... set column=column - {....} where ...".  This syntax should
also be supported for map columns.  This would be especially useful for prepared statements
(I know that you can use "set column[...] = null" to remove items in an update statement,
but that only works for one element at a time).
