Aggregate function that calculates the minimum across a group of values.
Example:
```
SELECT min(salary) FROM employees;
```
```
SELECT department, min(salary) FROM employees GROUP BY department;
```
If you need non-aggregate function to choose a minimum of two values, see `least`:
```
SELECT least(a, b) FROM table;
```
