dynamic partition pruning info doesn't appear in some cases

## Enhancement

```
use test;
create table t (a int, b int) partition by range (a) (partition p0 values less than (100), partition p1 values less than (200), partition p2 values less than (300), partition p3 values less than maxvalue);
analyze table t;
explain select * from t where a > 150;
select connection_id();
select * from t where a > 150;
explain for connection 4808316080869081497;
```
When executing `explain select * from t where a > 150`, dynamic partition pruning info `partition:p1,p2,p3` appears in `access object`.

However, when executing `explain for connection 4808316080869081497`, dynamic partition pruning info doesn't appear.

On dashboard, when using visual plan, we can see dynamic partition pruning info in `Access Object`.

However, when using text plan, we cannot see dynamic partition pruning info.
