Review Comment:
For postgresql https://www.postgresql.org/docs/8.4/intarray.html
it has three ways to sort an array
```
sort(int[], text dir) | int[] | sort array — dir must be asc or desc |
sort('{1,2,3}'::int[], 'desc') | {3,2,1}
sort(int[]) | int[] | sort in ascending order | sort(array[11,77,44]) |
{11,44,77}
sort_asc(int[]) | int[] | sort in ascending order | |
sort_desc(int[]) | int[] | sort in descending order |
```
