I found another piece of code that might need updating, or at least the
comment.

In MergeAttributes(), in the part that merges the specified column
definitions into the inherited ones, it says

/*
* Identity is never inherited. The new column can have an
* identity definition, so we always just take that one.
*/
def->identity = newdef->identity;

This is still correct for regular inheritance, but not for partitioning.
I think for partitioning, this is not reachable because you can't
specify identity information when you create a partition(?). So maybe
something like

if (newdef->identity)
{
Assert(!is_partioning);
/*
* Identity is never inherited. The new column can have an
* identity definition, so we always just take that one.
*/
def->identity = newdef->identity;
}

Thoughts?
