Imagine a table named Person with "first_name" and "age".
Now let's make it fancy and put a "mother" and "father" field that is
a reference to the own table (Person). And to get even fuzzier, let's
drop in some siblings:
CREATE TABLE person(
id bigint PRIMARY KEY,
first_name TEXT,
age INT,
mother bigint REFERENCES person,
father biging REFERENCES person,
siblings array of bigints (don't remember the syntax, but you get the point)
);
Well, this is ok, but imagine a search for "brothers of person id
34". We would have to search inside the record's 'siblings' array. Is
this a bad design? is this going to be slow?
What would be a better design to have these kind of relationships?
(where you need several references to rows inside the table we are).
Thanks for any help,
Rodrigo
