Normal SQL queries return rows where each row is independent of the other returned rows. SQL window functions allow queries to return computed columns based on values in other rows in the result set. This presentation explains the many window function facilities and how they can be used to produce useful SQL query results.

This presentation needs 65 minutes so has to be before lunch, a break, or at the end of the day. Slides are at https://momjian.us/main/writings/pgsql/window.pdf
