parent and child table foreign key

I currently have a parent table:

CREATE TABLE members (
     member_id SERIAL NOT NULL, UNIQUE, PRIMARY KEY
     first_name varchar(20)
     last_name varchar(20)
     address address (compsitie type)
     contact_numbers varchar(11)[3]
     date_joined date
     type varchar(5)
 );
 
 CREATE TABLE basic_member (
 activites varchar[3]) // can only have 3 max activites
 INHERITS (members)
 );
 
 CREATE TABLE full_member ( 
 activities varchar[]) // can 0 to many activities
 INHERITS (members)
 );
 

I also have another table called

CREATE TABLE planner (
     day varchar(9) FOREIGN KEY REFERENCES days(day)
     time varchar(5) FOREIGN KEY REFERENCES times(time)
     activity varchar(20) FOREIGN KEY REFERENCES activities(activity)
     member bigint FOREIGN KEY REFERENCES members(member_id)
 
 ALTER TABLE planner ADD CONSTRAINT pk_planner PRIMARKY KEY (day,time,activity,member);
 

I am currently trying to add with

INSERT INTO planner VALUES ('monday','09:00','Weights',2);
 

I have added a set into full_members with

INSERT INTO full_members 
 VALUES (Default, 'Hayley', 'Sargent', (12 Forest Road','Mansfield','Nottinghamshire','NG219DX'),'{01623485764,07789485763,01645586754}',20120418,'Full');
 

My insert is currently not working
