Example SQL query to convert Cayenne GPS location into PostGIS point:
```sql
WITH gps(alt, lat, lon) AS
(SELECT
CAST (object -> 'gpsLocation' -> '1' ->> 'altitude' AS FLOAT),
CAST (object -> 'gpsLocation' -> '1' ->> 'latitude' AS FLOAT),
CAST (object -> 'gpsLocation' -> '1' ->> 'longitude' AS FLOAT)
FROM event_up)
SELECT ST_MakePoint(lon, lat, alt)
FROM gps;
```
`CREATE EXTENSION postgis;` must be run on each database, not just the PostgreSQL instance.
