CREATE TABlE x(
          id int2 generated by default as identity
          (start 5) 
           primary key,
           name varchar(5))

Answer 1

From here Info functions:

select pg_get_serial_sequence ('x', 'id' );

 pg_get_serial_sequence     
--------------------------------
 <some_seq_name>


--Then

Select * from <some_seq_name>;
