В то время как PostgreSQL быстро развивается и становится все более мощным инструментом, все больше и больше компаний предпочитают ее проприетарным СУБД в попытке сократить расходы. Все больше и больше ИТ-менеджеров ищут сотрудников, знакомых с PostgreSQL. Все больше и больше потенциальных кандидатов учатся использовать PostgreSQL самостоятельно и упускают возможность получить от нее максимальную отдачу. В большинстве случаев книга об оптимизации рассматривается как книга для администраторов баз данных. Поскольку наша цель состоит в том, чтобы доказать, что оптимизация – это больше, чем просто создание индексов, мы надеемся, что книга будет полезна для более широкой аудитории. Эта книга предназначена для ИТ-специалистов, работающих с PostgreSQL, которые хотят разрабатывать производительные и масштабируемые приложения. Она для всех, чья должность содержит слова «разработчик базы данных» или «администратор базы данных», и для серверных разработчиков, которые взаимодействуют с базой данных.
