Question

In postgres if i have "id SERIAL PRIMARY KEY" and

some other VARCHAR UNIQUE NOT NULL data. why does the id keep incrementing when i try to add some non unique piece of data. would it be possible to make it so that the id would only increment when all the conditions have been met to even be able to add another row to the table?

yeah if u have some conditions for what data each row should have and if u try to add sth where these conditions arent met it takes up that id and it could never be used again
