```sql
localhost=# select 1 / 0;
ERROR: 22012: division by zero
LOCATION: int4div, int.c:824
```
Hmmm:
```sql
localhost=# select 1 / NULL;
┌──────────┐
│ ?column? │
├──────────┤
│ ¤ │
└──────────┘
(1 row)
Time: 7.067 ms
```
Ergo:
```sql
localhost=# select 1 / NULLIF(0, 0);
┌──────────┐
│ ?column? │
├──────────┤
│ ¤ │
└──────────┘
(1 row)
Time: 0.303 ms
```
