Neil,

Are you wanting to use postgis as a tileindex for a raster or a vector
layer?  I only have experience doing this for raster layers, but it might
also work for vector layers.

Generally if you want to use postgis for a tileindex, you need to create
a seperate tileindex layer and then reference that layer by name in the
TILEINDEX keyword of the tiled layer.

Best regards,
