pg-setup

pg-setup — set up a new Postgres Pro database cluster and manage the corresponding service

Synopsis

pg-setup initdb [initdb_options]

pg-setup find-free-port

pg-setup set-server-port port

pg-setup set parameter value

pg-setup service service_option

pg-setup tune conf

Description

pg-setup is a shell script provided in the Postgres Pro distribution to automate database cluster setup on Linux systems. This script is provided as part of the postgrespro-std-12-server package. Once Postgres Pro is installed, you can find pg-setup in the install-dir/bin directory, where install-dir is /opt/pgpro/std-12.

pg-setup must be run as root, but performs database administration operations as user postgres. You can run this script with different options to:

initialize the database cluster
configure the database cluster for a specific Postgres Pro product
check for available ports and change the port used by Postgres Pro server
enable/disable automatic startup of Postgres Pro service
start, stop, or restart Postgres Pro service

Options

pg-setup accepts the following command-line arguments:

initdb [--tune=conf] [initdb_options]

Initialize the database cluster on behalf of the postgres user.

By default, the database cluster, configured for your Postgres Pro distribution, is initialized in the /var/lib/pgpro/std-12/data directory, with checksums enabled, auth-local parameter set to peer, and auth-host parameter set to md5. Localization settings are inherited from the LANG environment variable for the current session. All the LC_* environment variables are ignored. Optionally, you can provide initdb options to customize the installation.

If the default database is created using pg-setup, the path to its data directory is stored in the /etc/default/postgrespro-standard-12 file, so all the subsequent pg-setup commands, as well as any commands that manage Postgres Pro service, affect this database only. You cannot manage several databases using pg-setup.

The --tune option sets the specified configuration for the database cluster. Predefined values of conf depend on the Postgres Pro edition and can be 1c, std or ent. The value of 1c can be specified for any product. By default, the database cluster is configured for your Postgres Pro Standard edition. If you provide a value different from any predefined, the cluster will get non-customized configuration settings.

For systems where more than one database server and/or application will run, you may need to adjust the configuration since pg-setup chooses the configuration settings depending on hardware characteristics, assuming that the system will use only one database server.

find-free-port

Search for a free port on your system. This option is useful if you are going to install more than one server instance, or the default 5432 port is used by another program.

set-server-port port

Specify the port number on which the server will listen for connections. Use this option to avoid conflicts if you are installing more than one server instance on the same system.

Default: 5432

set name value

Set the specified configuration parameter to the provided value in the postgresql.conf file. If this parameter has been already defined by the ALTER SYSTEM command, its previous value is removed from the postgresql.auto.conf file.

service service_option

Manage Postgres Pro service using one of the following options:

enable — enable automatic service startup upon system restart.
disable — disable automatic service startup upon system restart.
start — start the service.
stop — stop the service.
condrestart — restart the service if it is running when pg-setup is invoked.
status — return the Postgres Pro service status.

Notes

If you are installing Postgres Pro from the postgrespro-std-12 package, pg-setup is invoked automatically with the default settings. As a result, the database cluster is initialized and the default database is created in the /var/lib/pgpro/std-12/data directory, Postgres Pro service autostart is enabled, and the service is started.

If you are installing Postgres Pro server directly from the postgrespro-std-12-server package, you can run this script manually to initialize the database cluster or manage the Postgres Pro service.

For details on binary installation specifics on Linux, see Section 16.1.
