# PostgreSQL Module Module

[![Build Status](https://travis-ci.org/silverstripe/silverstripe-postgresql.png?branch=master)](https://travis-ci.org/silverstripe/silverstripe-postgresql)
[![SilverStripe supported module](https://img.shields.io/badge/silverstripe-supported-0071C4.svg)](https://www.silverstripe.org/software/addons/silverstripe-commercially-supported-module-list/)

## Maintainer Contact

 * Sam Minnee (Nickname: sminnee) <sam@silverstripe.com>

## Requirements

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

## Installation

```
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](https://docs.silverstripe.org/en/4/getting_started/environment_management) 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](docs/en/README.md) 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.

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.

Updated supported SS release in README 2015-11-02 20:45:29 +01:00			`* SilverStripe 4.0`
API Increased support to 9.2 Anything older than 9.3 is unsupported by Postgres: https://www.postgresql.org/support/versioning/. I don't think we should claim support in our module for unsupported versions, particularly if we don't have CI on them. Since we're only running CI on 9.2 at the moment, that's the safe claim for our module support, even though it's already unsupported by Postgres. See https://docs.travis-ci.com/user/database-setup/#using-a-different-postgresql-version I'll raise a separate ticket about testing and supporting newer versions, it's out of scope for this PR. 2019-09-03 05:41:23 +02:00			`* PostgreSQL >=9.2`
