PostgreSQL ima mehanizam za nasleđivanje između tabela (https://www.postgresql.org/docs/10/ddl-inherit.html)
Primer roditeljske tabele cities i deteta capitals:
CREATE TABLE cities ( name text, population float, altitude int -- in feet ); CREATE TABLE capitals ( state char(2) ) INHERITS (cities);
Dokumentacija PostgreSQLa kaže da postoji 1 ograničenje tj. mana u konceptu nasleđivanja tabela, a to je:
A serious limitation of the inheritance feature is that indexes (including unique constraints) and foreign key constraints only apply to single tables, not to their inheritance children.
