Install dummy package and sources from TYPO3 as usual.

Starting from TYPO3 4.4, the process is fully automated using 1-2-3 installer. Manual process is kept as reference for TYPO3 4.3.

1-2-3 Installer

Compatibility Tuning

You are strongly advised to run SQL scripts located in directory dbal/res/postgresql/ to ensure best compatibility with TYPO3.

[TYPO3 4.3] Installing and Configuring ADOdb and DBAL

Edit file typo3conf/localconf.php:

• Append adodb,dbal to $TYPO3_CONF_VARS['EXT']['extList'] and to $TYPO3_CONF_VARS['EXT']['extList_FE']
• Add code below to end of file:

$TYPO3_CONF_VARS['EXTCONF']['dbal']['handlerCfg'] = array(
        ’_DEFAULT’ => array(
                ’type’ => ’adodb’,
                ’config’ => array(
                        ’driver’ => ’postgres’,
                )
        ),
);

[TYPO3 4.3] Configuring Database Access

Edit typo3conf/localconf.php again and add these lines:

$typo_db_username = 'username';
$typo_db_password = 'password';
$typo_db_host = 'localhost';
$typo_db = 'database';

[TYPO3 4.3] Configuring TYPO3

Now you should be able to access the install tool (not the 1-2-3 wizard) from server/typo3/install/ and configure TYPO3 as usual.

Patching Core

As of TYPO3 4.3, DBAL system extension is now included as svn:externals into TYPO3 core. Meaning it will potentially be updated with new releases to fix bugs. If you find a bug, please report it to  DBAL bugtracker (make sure to choose subproject tx_dbal).

If you need the most up-to-date version of DBAL, then you should consider using its trunk version with a subversion check-out into typo3conf/ext/dbal (which will override the system version). SVN URL is:

https://svn.typo3.org/TYPO3v4/Extensions/dbal/trunk

You should consider then consider using trunk version of following files too, in typo3_src:

• t3lib/class.t3lib_db.php
• t3lib/class.t3lib_sqlparser.php

Installing RealURL

Nothing special anymore, SQL parser is finally able to deal with length restriction on indexes and as such you just have to load RealURL and enjoy!
