[postgis-users] Finding object that cover multiple polygons

I am working with some parcel data and building outlines. I'd like to
associate an outline to a parcel if it is located mostly in the parcel.
Buildings completely within the parcel can easily be found with
st_contains. How do I find buildings if they are just over the parcel
boundary. For example, in the first screenshot [1] the outline is just over
the boundary. I'd like to be able to run a query that would find those that
are just over. In a second example, this building [2] sits in the middle of
two parcels. I can safely ignore it.

Thanks,
Clifford
