Any psql script would be building and running SQL queries so I fail to see how that has any impact of the point being made. Edit: The argument is that there are operations that should be done in the SQL layer and it is worth time learning enough about that layer to understand when and how to use it for computation. Once you learn that, it isn't really relevant if you are using psql or some other client library to build those queries.
