[postgis-users] Google Maps Polyline to Postgis with Java/Hibernate

[Jason Greenlaw - NOAA Affiliate]

There may be a better solution, but what I've done in the past with
JPA/Hibernate is to create a varchar field that you can populate with the
WKT representing the polyline (represented in WKT as a LINESTRING), then
configure an 'AFTER INSERT OR UPDATE' trigger which updates the actual
geometry column with the result of ST_GeometryFromText(wkt, srid).
