pg_isready: Check connection with a specific hostname and port.
$ pg_isready --host=${hostname} --port=${port}
try on your machine
This command, "pg_isready --host=${hostname} --port=${port}", is used to check the status of a PostgreSQL database server.
Here's a breakdown of each part of the command:
- "pg_isready" is the name of the command-line utility used to check the database server's readiness.
- "--host=${hostname}" specifies the hostname or IP address of the PostgreSQL server that you want to check. The "${hostname}" is a placeholder that should be replaced with the actual hostname or IP address.
- "--port=${port}" specifies the port number on which the PostgreSQL server is running. The "${port}" is a placeholder that should be replaced with the actual port number.
When you run this command, it will reach out to the specified PostgreSQL server and check if it is accepting connections and is ready to serve queries. The command will display the status of the server, whether it is accepting connections or not.
Note: Make sure to replace "${hostname}" and "${port}" with the actual values specific to your PostgreSQL server configuration.
