👉 The word "postgresql.conf" is a configuration file used in PostgreSQL for database management. It defines settings such as connections, databases, tables, indexes, etc., that are specific to PostgreSQL. Detailed definitions include: - `POSTGRES` specifies PostgreSQL version. - `DATABASES` defines a dictionary of default databases and their configuration options. - `USER`, `PASSWORD`, and `HOSTNAME` specify user credentials, password, and host address for connections to the database server. - `DATABASE_URL` is used to connect to the database through a URL. Example: To connect to PostgreSQL instance with username "postgres" and password "password", use this configuration: ``` POSTGRES VERSION 9.2 DATABASES: default: DB_USER postgres DB_PASSWORD password DB_HOST localhost DB_PORT 5432 DB_NAME example_database USER = postgres PASSWORD = password HOSTNAME = localhost:5432 DATABASE_URL = "postgresql://user:password@localhost/db_name" ``` Each field in this configuration is an important setting or option used for database management.
