Construct a Polygon from MinX, MinY, MaxX, MaxY, and an optional SRID.

## Signatures

```sql theme={"system"}
ST_MakeEnvelope(MinX: Double, MinY: Double, MaxX: Double, MaxY: Double)
```

```sql theme={"system"}
ST_MakeEnvelope(MinX: Double, MinY: Double, MaxX: Double, MaxY: Double, srid: Integer)
```

## Parameters
