Is there a way for me to generate an entity table diagram vis pgAdmin4 or PSQL ?
Just write the 5 or so tables out in a somewhat compressed format. Psql doesn’t and I don’t know about pgadmin
Here is a compressed format :
s_tutor
--------
zipcode(text)
tutor_id (I just checked this is becomes a 'serial id ?' based on the generated sql
ALTER TABLE public.s_tutor ALTER COLUMN tutor_id ADD GENERATED BY DEFAULT AS IDENTITY (
SEQUENCE NAME public.tutor_strtutorid_seq
START WITH 1
INCREMENT BY 1
NO MINVALUE
NO MAXVALUE
CACHE 1
);
tutor_subject
----------------
tutor_id
subject_Names
