How to avoid prefixing every table with schema name while creating new tables ?

Lets assume schema name is my_data. If we want to avoid prefixing every table with my_data while creating a new table, we can set it in the search_path.

 SET search_path TO my_data;

Now we can create a new table like this.

CREATE TABLE courses (
    id SERIAL PRIMARY KEY,
    course_name TEXT
);

By using the above code, courses table will be created in my_data by default.
