[D7] FieldInfoTestCase::testFieldMap array order causes test fail on PostgreSQL

Problem/Motivation

In PostgreSQL there is a failure in testFieldMap() of the FieldInfoTestCase test caused by inconsistent order of the array elements returned by field_info_field_map() function. This function calls $cache->getFieldMap() which afterwards executes the SELECT query. This SELECT query does not use ORDER BY so that the order in the results array is not guaranteed.

Test failure looks like this:

testFieldMap

fail: [Other] Line 1553 of modules/field/tests/field.test:
Value array (
  'field_2' => 
  array (
    'bundles' => 
    array (
      'test_cacheable_entity' => 
      array (
        0 => 'test_bundle',
      ),
      'test_entity' => 
      array (
        0 => 'test_bundle',
      ),
    ),
    'type' => 'hidden_test_field',
  ),
  'field_1' => 
  array (
    'bundles' => 
    array (
      'test_entity' => 
      array (
        0 => 'test_bundle_2',
        1 => 'test_bundle',
      ),
    ),
    'type' => 'test_field',
  ),
) is equal to value array (
  'field_1' => 
  array (
    'type' => 'test_field',
    'bundles' => 
    array (
      'test_entity' => 
      array (
        0 => 'test_bundle',
        1 => 'test_bundle_2',
      ),
    ),
  ),
  'field_2' => 
  array (
    'type' => 'hidden_test_field',
    'bundles' => 
    array (
      'test_entity' => 
      array (
        0 => 'test_bundle',
      ),
      'test_cacheable_entity' => 
      array (
        0 => 'test_bundle',
      ),
    ),
  ),
).
