Executing
SELECT createInstructor('ins1', 'First Instructor');
causes following error
ERROR: function createinstructor(unknown, unknown) does not exist LINE 1: select createinstructor('ins1', 'First Instructor'); ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts.
Fixed in the Introduction page on Wiki. I am closing this issue with a note that all docs are yet to be reviewed (for these and other potential issues) before the M1 release is finalized.

Qualifying the function with schema name works.
