I've highlighted obvious bad values. Other columns are wrong as well.Is this a PostgreSQL bug?FWIW, these aren't the results I see when executing your query on 14.13. I'm not sure what interface you're using to get those tables, but let's eliminate some buggy GUI and use psql instead.I've attached a script, could you send us back the output of it with something like?: psql -f lag_query.sql > lagscript.txtI've included a query to give us the EXPLAIN ANALYZE output too. The WHERE clause quals shouldn't get pushed down since the PARTITION BY clause does not contain all of those fields.David
