# ST_LineSegments

This function transforms a LineString containing multiple coordinates into an array of LineStrings, each with precisely two coordinates. The `lenient` argument, true by default, prevents an exception from being raised if the input geometry is not a LineString.

## Examples

```sql theme={"system"}
SELECT ST_LineSegments(
        ST_GeomFromWKT('LINESTRING(0 0, 10 10, 20 20, 30 30, 40 40, 50 50)'),
       false
    )
```

```
[LINESTRING (0 0, 10 10), LINESTRING (10 10, 20 20), LINESTRING (20 20, 30 30), LINESTRING (30 30, 40 40), LINESTRING (40 40, 50 50)]
```

```sql theme={"system"}
SELECT ST_LineSegments(
        ST_GeomFromWKT('POLYGON((0 0, 10 0, 10 10, 0 10, 0 0))')
    )
