Thread: Analyze Explanation

When I run Analyze I get the following notice repeated for many of my
tables:

NOTICE:   no notnull values, invalid stats

Is this just refering to my empty tables?

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.

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.
