I've tried to using the newer definition:
id int GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY

Is there a way to define id columns to that when the database provides values,
it recognizes already existing values avoiding conflicts.
You'll need to run something like the below to set the next value to the max current value. You'll just have to figure out the name of the sequence that is automatically created whether you use the pseudo type serial, or the newer IDENTITY option. Both are implemented with a sequence.
--set sequence to max ID on a table
select setval( 'table_name_id_seq', ( select max(id) + 1 from table_name ) );
