after we support delta updae in #3053 , we shouldn't load the whole histogram when we find the table version updated. Every histogram has it's own version.

*: use column id to get stats instead of column offset ( #3019 )
...
Now we assume that the order of columns in stats matches the column offsets. It will return wrong stats sometimes.
If we analyze when a table is (c1, c2) and then drop c1, the c2's offset will become 0. But in stats the position of 0 is c1. I have added this case to test.
