PostGIS tile index example?

[Pericles S. Nacionales]

Does anyone have a working example of a PostGIS-based tileindex?  If so, 
would you care to share how you do it (provide an example mapfile)?  I 
converted one of my shapefile-based tindex to PostGIS table and tried to 
use it but it didn't work.  Would I need to implement the tindex as a 
spatio-temporal tindex (as implemented for WCS support)?

Any help would be appreciated.

Thanks,
