Pgstatspack errors in log files

Hi All

        I am hoping someone else have had this before.

        We have configured pgstatspack to run on one of many database servers as we want to test the impact and results before deploying to all servers.

        On the test server everything was working fine without any errors.

        However, we then deployed this to one of the production server and even though we are getting relevant results, snapshots,etc... the following errors appear in the Postgresql log files.
   
        Does anybody know why we would be getting this and how to resolve this. I would really appreciate the help.
