The following will give some sample inputs and outputs that you can use to estimate the correctness of your views and functions. At present it just shows output from a few simple queries.
These examples are by no means exhaustive, and more cases will be used in the auto-marking; it is up to you to perform comprehensive checking of your solution.
Note that the default behaviour when you raise an error is to print a line giving you the CONTEXT in the PLpgSQL code where the error was raised. We did not show the CONTEXT message in the examples below. For you to prevent the message, use the psql command:
\set verbosity terse
Of course, this will probably prevent the CONTEXT message appearing if your code has a genuine error, so rather than turning the message off, you could always just ignore it. Whether it's on or off does not affect the auto-marking.
