Description:
In Section 3.5 Window Functions, the sentence that currently says:
"As shown here, the rank function produces a numerical rank for each
distinct ORDER BY value in the current row's partition..."
should say:
"As shown here, the rank function produces a numerical rank for each
distinct depname value in the current row's partition..."
https://www.postgresql.org/docs/current/tutorial-window. html
If we wanted to name the relevant column it would be salary, not depname. It is the column(s) in the order by that matter here. Or I suppose the combination of depname and salary. Though it was already covered that each partition resets all aggregates. Here we are not talking about reset but when something increments.
