The new FusionTablesLayer in Google Maps API version 3 has an option to display as a heatmap instead of points. Here's the example. Is there a way to get the heat map display without using Fusion Tables (but still using the Google Maps API)? I already have my data in my own PostgreSQL/Postgis database. Having Google do the heatmap a preferred alternative to implementing my own tile server.

A:
You might want to try an external service or library, like Heat Map API. Apart from Fusion Tables Google does not offer a heat mapping service that can be rendered on the Maps API.

Yes, that appears to be the case, at least currently. It wouldn't surprise me if they eventually enable the same sort of thing for KML based overlays, seeing that KML and fusion tables both have the opportunity to be processed and rendered on the server side. Some day, I suppose.
