Google Maps now allows the use of the KML File Format, which is previously only for Google Earth.
Postgis features the command AsKML() which outputs the geometry part of KML and automatically transforms the data to the correct projections. I used this successfully to visualize community GIS data. A few lines of PHP did the job, but any scripting language can be used. All you have to do is to write out the attribute data you want (HTML syntax) along with the output of AsKML(), structure the data into groups and attach styles. You can use network links to combine separate topics.
