Move all elements toward another schema?

[celati Laurent <laurent.celati@xxxxxxxxx>]

Good afternoon,

With postgresql 13, I want to find a way to move 100 tables from schema 'A' to schema 'B'. Not just data. But also indexes, primary keys, constraints (INCLUDING ALL). 

As far as i know, this piece of code would move the data. But how to also move indexes, constraints, primary key?

DO
$$
DECLARED
     row record;
BEGIN
     FOR row IN SELECT tablename FROM pg_tables WHERE schemaname = 'A' -- and other conditions, if needed
     LOOPS
         EXECUTE format('ALTER TABLE A.%I SET SCHEMA [B];', row.tablename);
     END LOOP;
END;
$$;

Thanks so much.
