Now, write your migrations in PostgreSQL. For example

-- ./db/migrations/up/1525396716884_create_table_companies.sql 
 
CREATE TABLE public.companies (
  id UUID PRIMARY KEY DEFAULT uuid_generate_v4(),
  name TEXT NOT NULL UNIQUE,
  active BOOLEAN NOT NULL DEFAULT TRUE
);
 
CREATE UNIQUE INDEX companies_id_idx ON public.companies (id);
CREATE UNIQUE INDEX companies_name_idx ON public.companies (name);
CREATE INDEX companies_active_idx ON public.companies (active);
-- ./db/migrations/down/1525396716884_create_table_companies.sql
