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.

## Requirements
|
||||
|
||||
* SilverStripe 4.0
|
||||
* PostgreSQL 8.3.x or greater must be installed
|
||||
* PostgreSQL <8.3.0 may work if T-Search is manually installed
|
||||
* Known to work on OS X Leopard, Windows Server 2008 R2 and Linux
|
||||
* PostgreSQL >=9.2
|
||||
* Note: PostgreSQL 10 has not been tested
|
||||
|
||||
## Installation
|
||||
|
||||
1. Install via composer `composer require silverstripe/postgresql` or extract the contents
|
||||
so they reside as a `postgresql` directory inside your SilverStripe project code
|
||||
2. Open the installer by browsing to install.php, e.g. http://localhost/silverstripe/install.php
|
||||
3. Select PostgreSQL in the database list and enter your database details
|
||||
```
|
||||
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

||||
|
||||

# PostgreSQL Database Module
|
||||
|
||||
SilverStripe now has tentative support for PostgreSQL ('Postgres').
|
||||
|
||||
## Requirements
|
||||
|
||||
SilverStripe 2.4.0 or greater. (PostgreSQL support is NOT available
|
||||
in 2.3.).
|
||||
|
||||
SilverStripe supports Postgres versions 8.3.x, 8.4.x and onwards.
|
||||
Postgres 8.3.0 launched in February 2008, so SilverStripe has a fairly
|
||||
modern but not bleeding edge Postgres version requirement.
|
||||
|
||||
Support for 8.2.x is theoretically possible if you're willing to manually
|
||||
install T-search. 8.2.x has not been tested either, so there may be other
|
||||
compatibility issues. The EnterpriseDB versions of Postgres also work, if
|
||||
you'd prefer a tuned version.
|
||||
|
||||
## Installation
|
||||
|
||||
You have three options to install PostgreSQL support with SilverStripe.
|
||||
|
||||
### Option 1 - Installer
|
||||
|
||||
The first option is to use the installer. However, this is currently only
|
||||
supported since SilverStripe 2.4.0 beta2 (or using the daily builds).
|
||||
|
||||
1. Set up SilverStripe somewhere where you can start the installer - you
|
||||
should only see one database “MySQL” to install with.
|
||||
2. Download a copy of the “postgresql” module from here:
|
||||
http://silverstripe.org/postgresql-module
|
||||
3. Extract the archive you downloaded. Rename the directory from
|
||||
“postgresql-trunk-rxxxx” to “postgresql” and copy it into the SilverStripe
|
||||
directory you just set up
|
||||
4. Open the installer once again, and a new option “PostgreSQL” should appear.
|
||||
You can now proceed through the installation without having to change any code.
|
||||
|
||||
### Option 2 - Manual
|
||||
|
||||
The second option is to setup PostgreSQL support manually. This can be achieved
|
||||
by following these instructions:
|
||||
|
||||
1. Set up a fresh working copy of SilverStripe
|
||||
2. Download a copy of the “postgresql” module from here: http://silverstripe.org/postgresql-module
|
||||
3. Extract the archive you downloaded. Rename the directory from
|
||||
“postgresql-trunk-rxxxx” to “postgresql” and copy it into the SilverStripe
|
||||
directory you just set up.
|
||||
4. Open up your mysite/_config.php file and add (or update) the $databaseConfig
|
||||
array like so:
|
||||
|
||||
> $databaseConfig = array(
|
||||
> 'type' => 'PostgreSQLDatabase',
|
||||
> 'server' => '[server address e.g. localhost]',
|
||||
> 'username' => 'postgres',
|
||||
> 'password' => 'mypassword',
|
||||
> 'database' => 'SS_mysite'
|
||||
> );
|
||||
|
||||
Finally, visit dev/build so that SilverStripe can build the database schema and
|
||||
default records.
|
||||
|
||||
### Option 3 - Environment file
|
||||
|
||||
Finally, the third option is to change your environment to point to
|
||||
PostgreSQLDatabase as a database class. Do this if you're currently using an
|
||||
_ss_environment.php file.
|
||||
|
||||
1. Download a copy of the “postgresql” module from here: http://silverstripe.org/postgresql-module
|
||||
2. Extract the archive you downloaded. Rename the directory from
|
||||
postgresql-trunk-rxxxx” to “postgresql” and copy it into your SS directory
|
||||
3. Add the following to your existing _ss_environment.php file:
|
||||
|
||||
> define('SS_DATABASE_CLASS', 'PostgreSQLDatabase');
|
||||
|
||||
Last steps:
|
||||
|
||||
1. Ensure your SS_DATABASE_USERNAME and SS_DATABASE_PASSWORD defines in
|
||||
_ss_environment.php are correct to the PostgreSQL server.
|
||||
2. Ensure that your mysite/_config.php file has a database name defined, such
|
||||
as “SS_mysite”.
|
||||
3. Visit dev/build so that SilverStripe can build the database schema and
|
||||
default records

## 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.
