TCP 5432
Synopsis
- TCP port 5432 is the default listening port for the PostgreSQL database server, using the PostgreSQL frontend/backend wire protocol.
- Real-world deployments include community PostgreSQL on Linux/Windows/macOS and EnterpriseDB Postgres Advanced Server.
- Managed services exposing PostgreSQL on 5432 include Amazon RDS and Aurora PostgreSQL, Google Cloud SQL for PostgreSQL, Azure Database for PostgreSQL, Heroku Postgres, Supabase, and Neon.
- PostgreSQL-based systems commonly using 5432 include Greenplum Database (master node by default), as well as PostgreSQL instances with extensions like TimescaleDB or PostGIS.
- Client software such as psql, pgAdmin, libpq-based applications, and JDBC/ODBC drivers connect to servers on 5432 by default.
- Security note: port 5432 is frequently targeted for brute-force attacks against PostgreSQL; compromised superuser accounts are often abused to run OS commands (e.g., via COPY FROM PROGRAM or untrusted PLs) for data theft or malware deployment.
