Scope
Port associations on this page are community-database references (common usage), not a live measurement of any machine; confirm with the official documentation before deployment.
Frequently asked questions
What port does PostgreSQL use?
PostgreSQL commonly uses these ports: 5432. The default port is 5432. These are community database references — actual configuration may differ.
How do I check if PostgreSQL is running?
Run sudo ss -tlpn 'sport = :5432' on the server to check for listening processes on these ports. Also use systemctl status <service> to check the service state. Without root you may not see other users' processes. A listening port alone does not prove the software identity — verify with the config file and process name.
What category does PostgreSQL belong to?
PostgreSQL belongs to the Database category. This page lists the software's port associations and their roles.
