Issue:
Issue parsing `tstzrange` columns on postgres
**Fully reproducible code snippet**

```sql
CREATE TABLE public.y (
    x tstzrange NOT NULL
);
```

```python
import sqlglot
from sqlglot.dialects import Postgres
content = sqlglot.parse("sql content here", Postgres)
```

Error:

```
sqlglot.errors.ParseError: Expecting ). Line 2, Col: 15.
  CREATE TABLE public.y (
    x tstzrange NOT NULL
);
```
