Could you check if it's technically possible to have a PK which consists of multiple columns one or more of which has AUTOINCREMENT? If yes, then it would be a breaking change since in this case, the PK will consist only declared for the autoincremented column.

That's currently not possible. It will result in a MappingException while generating the scheme:
"Single id is not allowed on composite primary key in entity...."

I was talking about SQLite itself, not the ORM.

From what I can read online it's either a composite key, or a single autoincrement key. The combination seems not possible in SQLite.

Then we're not breaking anything. Sounds good.

Why do we need to cover this case with a test? Is it something DBAL users could/would want to rely on?

I think this test was added by the original author to check that the default behavior of SQLite wasn't altered in cases it shouldn't.

{
$table = new Schema\Table('test_pk_auto_increment');
$table->addColumn('id', 'integer');
$table->addColumn('text', 'text');
$table->setPrimaryKey(['id']);
$this->_sm->dropAndCreateTable($table);

$query = $this->_conn->query('SELECT id FROM test_pk_auto_increment WHERE text = "2"');
$query->execute();
$lastUsedIdAfterDelete = (int) $query->fetchColumn();

// with an empty table, non autoincrement rowid is always 1
$this->assertEquals(1, $lastUsedIdAfterDelete);
