dbexamplelocal5432

dbexamplelocal5432 is a placeholder name used in database tutorials and sample code to refer to a local PostgreSQL instance listening on the default port 5432. The label combines a generic database prefix (dbexample), the local host indicator (local), and the conventional PostgreSQL port number (5432). While not an official product or standard, it appears in instructional materials to illustrate how a client connects to a database on the local machine.

In everyday use, this would be a development database running on the developer's computer. Applications connect via the host localhost or 127.0.0.1 and port 5432, with a database name such as dbname, a user name, and a password. A typical connection string for PostgreSQL is postgresql://user:password@localhost:5432/dbname, though variations exist for libraries and environments.

Security and configuration considerations apply. A local instance should be protected from remote access by configuring pg_hba.conf and listening addresses, using strong credentials, and enabling TLS if remote connections are possible. Production deployments should use a different host and more robust access controls; the dbexamplelocal5432 label is intended for learning and testing rather than production use.

Limitations and variations: depending on the educational material, the actual database name, user, and password may differ; port 5432 is the default for PostgreSQL but may be changed. It is typical to see this label in tutorials showing steps such as creating schemas, running migrations, and performing queries.
