1. Create a database in PostgreSQL named courses. 2. The database will contain three relations with the schema: Likes (student, professor) Enrolls (student, course) Teaches (professor, course) teaches professor enrolls student course course likes student professor Q6 Find all students that enrolled in some course taught only by professors that they like. 07 Find all students that enrolled in some course taught by some professor that they don't like. Q8 Find all students that enrolled in some course taught only by professors that they don't like.
