DIM: Warnings while installing

bytescapes

I'm in the process of reinstalling my complete DAZ library (don't ask), and I've noticed that the DAZ Install Manager periodically throws warnings of the form:

   WARNING: /src/dzpostgresqlobjectdatabase.cpp(37): db fetch error: Attempt to convert null to long long

It happens on a small number of products, and there are usually multiple WARNING lines of this type before it reports that the product was installed successfully.

Is this anything I need to worry about, or is it a transient error that can be safely ignored? And if it does indicate an actual problem, what's the best way to resolve it?
