Connecting to postgresql directly

Is there a way to connect/append data from PostgreSQL directlyto paraview objects?

I am visualising 3D objects in paraview, each object’s file name is the unique identifier.
The unique identifier is the same in the PostgreSQL database, rather than exporting to csv is there anyway to connect it directly? We are adding new 3D objects every year and constantly updating the information associated with them.

Not possible yet. It definitely could be done in a ParaView plugin if you are a C++ (or Python) developer.
