pg_ctl:tldr:92f96
pg_ctl: Reload the PostgreSQL server configuration.
$ pg_ctl -D ${data_directory} reload
try on your machine
This command is used to send a reload signal to a running PostgreSQL database cluster.
Here's what each part of the command means:
pg_ctl
: This is the command-line utility used to control PostgreSQL database clusters.-D ${data_directory}
: This specifies the path to the data directory of the PostgreSQL cluster.${data_directory}
is typically replaced with the actual path to the data directory.reload
: This is the argument passed topg_ctl
that tells it to send a reload signal to the PostgreSQL cluster.
When the pg_ctl
command is executed with the -D ${data_directory} reload
arguments, it will locate and connect to the running PostgreSQL cluster using the specified data directory and instruct it to reload its configuration files. This can be useful after making changes to the configuration files (e.g., postgresql.conf
) to apply those changes without restarting the entire PostgreSQL cluster.

never run a command you are not sure if it is safe.
