i am making a db and am creating a table from a csv file. when writing my column names i see a PK toggle. do i have to select that for the db to know the pk of that table? or does postgres already know what it will be?
please eli5/not-too-complex, i’m a beginner at making my own tables.
i’m not sure how to tell it what the fks are if i have to tell it the pks so if someone can help that’ll be awesome too. thanks!
