An admitted newbie to postgresql I am trying to commit a new design
my development server using pgAdminII.

Everything appears to work OK but I am having real grief with my
SQL generating errors - most of which I have cleared myself but
one that I am unsure how to handle:

UNIQUE constraint for matching given keys for referenced table "staff"
not found

Below is the SQL code that I am tring to load to build out my database
skeleton:
