Tom,

My understanding is that now (as of 4.4 or 4.6?) tileindexes can
be any feature data source that works as a layer.  So PostGIS
should be fine.  However you would need to declare the tileindex
as a distinct layer and then reference it from the target raster layer.

However, I am less clear on how the WMS interaction would work.

Best regards,
