What is the default port number for PostgreSQL?

The correct answer is 5432, as this is the default port number for PostgreSQL. This port is specified in the PostgreSQL configuration files and is the standard through which clients connect to the PostgreSQL server. This default setting allows for seamless operation of database connections unless otherwise configured by the user.

Using the correct port number is crucial for database administration and application development, as it ensures that the communication between the application and the database can occur without issues. If a different port is configured, users must adjust their connection settings accordingly to avoid connection errors.

The other choices provided do not represent the default PostgreSQL port. For instance, 8060 and 8080 are commonly associated with web server applications and HTTP traffic, while 27000 is often associated with other database services, like those from Oracle. Thus, understanding the significance of the standard port for PostgreSQL is essential for anyone working in database management.
