В помощь специалистам, знакомым с устройством реляционных СУБД, планирующим переход на PostgreSQL, издательство «ДМК Пресс» выпустило книгу «PostgreSQL 15 изнутри». The exodus of western IT vendors from Russia has led to shrinkage of local enterprise database market. The way out is PostgreSQL, with major Russian financial and industrial corporations having migrated to the database without waiting for imported software products to “turn into a pumpkin”. However, it is no typical task for a corporation to maintain an opensource solution, tracking its development and ensuring guaranteed reliability of the system-level code. For PostgreSQL, those tasks are handled by Postgre Professional, a company offering the Postgres Pro database that is included into the Unified Registry of Russian Software Products.
