Description: Postmaster is the main process of the PostgreSQL server responsible for managing database connections and processes. This component is essential for the system’s operation, acting as an intermediary between clients and the database, ensuring that connection requests are handled efficiently. The Postmaster initiates other necessary processes for database operation, such as worker processes that execute queries and manage transactions. Additionally, it supervises these processes, ensuring they remain active and that system resources are managed properly. Its design allows PostgreSQL to handle multiple simultaneous connections, which is essential for applications requiring high availability and performance. In summary, the Postmaster is a critical component that ensures the stability and efficiency of the database server, facilitating interaction between users and stored data.
