Which port is designated for PostgreSQL?

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

Answer: (B)

PostgreSQL servers listen for client connections on a single TCP port by default, and the server starts on that designated port unless you change it. This port is the one officially associated with PostgreSQL in standard registries, so it’s the port that most clients assume when connecting to a PostgreSQL instance. You can alter it by setting the port parameter in the server’s configuration (postgresql.conf) and then updating any client connection strings to use the new port. The other ports listed correspond to other services, not PostgreSQL, so they don’t fit as the designated PostgreSQL port.
