Which port is commonly used by PostgreSQL?

• A. 5432
• B. 1194
• C. 6000
• D. 6789

Answer: (A)

PostgreSQL servers listen on a network port so clients can connect. By convention, the default listening port is 5432, which is the port most installations use unless it’s been changed. This means client applications connect to host:5432 to reach PostgreSQL. The other ports shown belong to different services (for example, 1194 is commonly used by OpenVPN and 6000 is associated with the X Window System), so they’re not the standard PostgreSQL port. If you haven’t changed it, you’ll be using 5432.
