Analyze Explanation

There's no such message in the core Postgres code. Perhaps it's coming
from an add-on, such as Postgis? If so, you should ping them about why
they think this notice is needed.

Is this just refering to my empty tables?

The PostGIS function compute_geometry_stats() logs such a message.
I'd guess you're using PostGIS and those tables have NULL in all
rows' geometry columns.
