Official description
PostgreSQL's optimized statistics on a table are visible as long as you have SELECT privilege on said table. A masked role can therefore read a limited subset of the data through the statistics view's histograms and mcvs. The vulnerability is resolved in PostgreSQL Anonymizer 3.3.0 and later versions.
