Without the fix running `SYMFONY_PHPUNIT_SKIPPED_TESTS='phpunit.skipped' php
./phpunit src/Symfony/Component/Lock/Tests/Store/DoctrineDbalPostgreSqlStoreTest.php`
without the pdo_pgsql extension enabled the generated skip file looked like this:

```
<?php return array (
  'PHPUnit\\Framework\\DataProviderTestSuite' =>
  array (
    'Symfony\\Component\\Lock\\Tests\\Store\\DoctrineDbalPostgreSqlStoreTest::testInvalidDriver' => 1,
  ),
  'Symfony\\Component\\Lock\\Tests\\Store\\DoctrineDbalPostgreSqlStoreTest' =>
  array (
    'testSaveAfterConflict' => 1,
    'testWaitAndSaveAfterConflictReleasesLockFromInternalStore' => 1,
    'testWaitAndSaveReadAfterConflictReleasesLockFromInternalStore' => 1,
    'testSave' => 1,
    'testSaveWithDifferentResources' => 1,
    'testSaveWithDifferentKeysOnSameResources' => 1,
    'testSaveTwice' => 1,
    'testDeleteIsolated' => 1,
    'testBlockingLocks' => 1,
    'testSharedLockReadFirst' => 1,
    'testSharedLockWriteFirst' => 1,
    'testSharedLockPromote' => 1,
    'testSharedLockPromoteAllowed' => 1,
    'testSharedLockDemote' => 1,
  ),
);
```

Thus, running the tests again with the extension enabled would only run 14
tests instead of the expected total number of 16 tests.

With the patch applied the generated skip file looks like this:

```
<?php return array (
  'Symfony\\Component\\Lock\\Tests\\Store\\DoctrineDbalPostgreSqlStoreTest' =>
  array (
    'testInvalidDriver with data set #0' => 1,
    'testInvalidDriver with data set #1' => 1,
    'testSaveAfterConflict' => 1,
    'testWaitAndSaveAfterConflictReleasesLockFromInternalStore' => 1,
    'testWaitAndSaveReadAfterConflictReleasesLockFromInternalStore' => 1,
    'testSave' => 1,
    'testSaveWithDifferentResources' => 1,
    'testSaveWithDifferentKeysOnSameResources' => 1,
    'testSaveTwice' => 1,
    'testDeleteIsolated' => 1,
    'testBlockingLocks' => 1,
    'testSharedLockReadFirst' => 1,
    'testSharedLockWriteFirst' => 1,
    'testSharedLockPromote' => 1,
    'testSharedLockPromoteAllowed' => 1,
    'testSharedLockDemote' => 1,
  ),
);
