Postgresql 1

Postgresql

On this page, $ means the command must be run as a user with adequate rights such as the postgresql user.

Filesystem preparation

In case a Btrfs filesystem is used, Copy-on-Write should be disabled first.

Initial setup

The database can be initialized using the following command. Locale defaults to current environment locale.

$ initdb --locale C.UTF-8 --encoding=UTF8 -D /var/lib/postgres/data --data-checksums

Postgresql can then be started using the postgresql systemd service.

Usage

Creating users

The following command can be used:

$ createuser [--interactive]

Additionnal options can be used to give permissions to the user (usually not needed).

Users can be deleted using the following command:

$ dropuser [-i/--interactive] [user]

Creating databases

The following command can be used:

$ createdb [-O owner] [dbname [description]]
