Review Comment:
I see that we are removing `COLUMN_STATS_ACCURATE` here, however, in the
corresponding q file, I see this comment:
```
-- rename a partition should not change its table, partition, and column
stats
alter table statsdb1.testpart1 partition (part = 'part1') rename to
partition (part = 'part11');
describe formatted statsdb1.testpart1;
```
So this seems like a behavioral change. I just want us to be sure that this
is what we intend to do as I see several other similar changes just below which
were due to renaming/replacing columns.

Review Comment:
Here we are printing empty `COLUMN_STATS_ACCURATE`. If it is easy to remove
them, maybe we should do that?
