Скрипт создания БД:
-- Create the database
CREATE DATABASE station;

-- Connect to the database
\c station;

-- Create the table for form submissions
CREATE TABLE form_submissions (
id SERIAL PRIMARY KEY,
from_location VARCHAR(255) NOT NULL,
to_location VARCHAR(255) NOT NULL,
departure_date DATE NOT NULL,
return_date DATE NOT NULL,
name VARCHAR(255) NOT NULL
