Doctrine PostgreSQL Default Schema Fix For Symfony

FixPostgreSQLDefaultSchemaListener.php

<?php

declare(strict_types=1);

namespace App\Doctrine\EventListener;

use Doctrine\DBAL\Schema\PostgreSQLSchemaManager;
use Doctrine\ORM\Tools\Event\GenerateSchemaEventArgs;

final class FixPostgreSQLDefaultSchemaListener
{
    /**
     * @throws \Doctrine\DBAL\Exception
     */
    public function postGenerateSchema(GenerateSchemaEventArgs $args): void
    {
        $schemaManager = $args
            ->getEntityManager()
            ->getConnection()
            ->createSchemaManager();

        if (!$schemaManager instanceof PostgreSQLSchemaManager) {
            return;
        }

        $schema = $args->getSchema();

        foreach ($schemaManager->listSchemaNames() as $namespace) {
            if (!$schema->hasNamespace($namespace)) {
                $schema->createNamespace($namespace);
            }
        }
    }
}

services.php

<?php

declare(strict_types=1);

use App\Doctrine\EventListener\FixPostgreSQLDefaultSchemaListener;
use Doctrine\ORM\Tools\ToolEvents;
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $configurator): void {
    $services = $configurator->services();

    $services
        ->set(FixPostgreSQLDefaultSchemaListener::class)
            ->tag('doctrine.event_listener', ['event' => ToolEvents::postGenerateSchema]);
};

services.yaml

services:
    App\Doctrine\EventListener\FixPostgreSQLDefaultSchemaListener:
        tags:
            - { name: doctrine.event_listener, event: postGenerateSchema }

@vasilvestre, had the same problem, i do this instead, and it work

        exec('bin/console doctrine:database:drop --force --env=test');
        exec('bin/console doctrine:database:create --env=test');
        exec('bin/console doctrine:migrations:migrate --env=test -n');

Your commands will work for new migration. But for existing db+already migrated migrations, it won't work. This gist will fix that problem too, I guess.

I've just upgraded from v2 to v3 and had to make changes to this listener. The main change was to:
foreach ($schemaManager->getExistingSchemaSearchPaths() as $namespace) {

to use listSchemaNames() instead:
foreach ($schemaManager->listSchemaNames() as $namespace) {

getExistingSchemaSearchPaths() is internal and listSchemaNames() is public. getExistingSchemaSearchPaths() also wasn't providing the expected set of namespaces.

Thank you @stetodd .

One more addition to the changes @stetodd suggested to remove usage of a deprecated methods from doctrine/orm 2.13: change ->getSchemaManager() into ->createSchemaManager().

Also, when using Symfony 5.3 or up (and yaml config) you can use a when@dev statement to add the listener like so:

when@dev:
    services:
        App\Doctrine\EventListener\FixPostgreSQLDefaultSchemaListener:
            tags:
                - { name: doctrine.event_listener, event: postGenerateSchema }

Created a new gist for a complete overview: https://gist.github.com/mvmaasakkers/7c28355715850d991fb9feb649e60463

Thank you all for the interest! I've updated the snippet to match the latest Doctrine contracts.

Can be configured right in attributes.

use Symfony\Component\DependencyInjection\Attribute\AutoconfigureTag;
use Symfony\Component\DependencyInjection\Attribute\When;

#[When('dev')]
#[AutoconfigureTag('doctrine.event_listener', ['event' => ToolEvents::postGenerateSchema])]
final class FixPostgreSQLDefaultSchemaListener
{
}

Using attributes to register the event listener per the documentation:

// FixPostgreSQLDefaultSchemaListener.php

#[AsDoctrineListener(event: ToolEvents::postGenerateSchema, connection: 'default')] 
final class FixPostgreSQLDefaultSchemaListener
{
    // implementation
}

With a WhenDev

<?php

declare(strict_types=1);

namespace App\Shared\Doctrine;

use Doctrine\Bundle\DoctrineBundle\Attribute\AsDoctrineListener;
use Doctrine\DBAL\Schema\PostgreSQLSchemaManager;
use Doctrine\ORM\Tools\Event\GenerateSchemaEventArgs;
use Doctrine\ORM\Tools\ToolEvents;
use Symfony\Component\DependencyInjection\Attribute\When;

#[When('dev')]
#[AsDoctrineListener(event: ToolEvents::postGenerateSchema, connection: 'default')]
final class FixPostgreSQLDefaultSchemaListener
{
    public function __invoke(GenerateSchemaEventArgs $args)
    {
        $schemaManager = $args
            ->getEntityManager()
            ->getConnection()
            ->createSchemaManager();

        if (!$schemaManager instanceof PostgreSQLSchemaManager) {
            return;
        }

        $schema = $args->getSchema();

        foreach ($schemaManager->listSchemaNames() as $namespace) {
            if (!$schema->hasNamespace($namespace)) {
                $schema->createNamespace($namespace);
            }
        }
    }
}

Im not proud of this - but for anyone wanting to not break schema tool operations doctrine:schema:create you can add a guard statement to the event listener limiting the fix to only be applied when running doctrine:migrations:diff

final class FixPostgreSQLDefaultSchemaListener
{
    /**
     * @throws \Doctrine\DBAL\Exception
     */
    public function postGenerateSchema(GenerateSchemaEventArgs $args): void
    {
        // Only apply this fix when using the doctrine:migrations:diff command
        if (
            !isset($_SERVER['argv'])
            || !is_array($_SERVER['argv'])
            || !in_array('doctrine:migrations:diff', $_SERVER['argv'], true)
        ) {
            return;
        }
