try on your machine

The command "pg_ctl -D ${data_directory} start" is used to start a PostgreSQL database server.

Here's a breakdown of the command:

"pg_ctl": It is the command-line utility program used to control various aspects of a PostgreSQL server, such as starting, stopping, or restarting.
"-D ${data_directory}": It specifies the data directory for the PostgreSQL server. The data directory is the location where all the database files, configuration files, and other data related to the server are stored.
"start": It is an argument passed to the pg_ctl command, indicating that the server should be started. When this argument is used, pg_ctl starts the PostgreSQL server with the specified data directory.

In summary, the command "pg_ctl -D ${data_directory} start" is used to start the PostgreSQL server using the specified "data_directory".
