PostgreSQL Module Module

Requirements

• SilverStripe 4.0
• PostgreSQL >=9.2
• Note: PostgreSQL 10 has not been tested

composer require silverstripe/postgresql

Configuration

Environment file

Add the following settings to your .env file:

SS_DATABASE_CLASS=PostgreSQLDatabase
SS_DATABASE_USERNAME=
SS_DATABASE_PASSWORD=

See environment variables for more details. Note that a database will automatically be created via dev/build.

Through the installer

Open the installer by browsing to install.php, e.g. http://localhost/install.php
Select PostgreSQL in the database list and enter your database details

Usage Overview

See docs/en for more information about configuring the module.

Known issues

All column and table names must be double-quoted. PostgreSQL automatically
lower-cases columns, and your queries will fail if you don't.

Collations have known issues when installed on Alpine, MacOS X and BSD derivatives
(see PostgreSQL FAQ).
We do not support such installations, although they still may work correctly for you.
As a workaround for PostgreSQL 10+ you could manually switch to ICU collations (e.g. und-x-icu).
There are no known workarounds for PostgreSQL <10.

Ts_vector columns are not automatically detected by the built-in search
filters. That means if you're doing a search through the CMS on a ModelAdmin
object, it will use LIKE queries which are very slow. If you're writing your
own front-end search system, you can specify the columns to use for search
purposes, and you get the full benefits of T-Search.

If you are using unsupported modules, there may be instances of MySQL-specific
SQL queries which will need to be made database-agnostic where possible.
