/**
 * Changes a field definition.
 *
 * IMPORTANT NOTE: To maintain database portability, you have to explicitly
 * recreate all indices and primary keys that are using the changed field.
 *
 * That means that you have to drop all affected keys and indexes with
 * \Drupal::database()->schema()->drop{PrimaryKey,UniqueKey,Index}() before
 * calling \Drupal\Core\Database\Schema::changeField().
 * To recreate the keys and indices, pass the key definitions as the optional
 * $keys_new argument directly to \Drupal\Core\Database\Schema::changeField().
 *
 * For example, suppose you have:
 * @code
 * $schema['foo'] = array(
 *   'fields' => array(
 *     'bar' => array('type' => 'int', 'not null' => TRUE)
 *   ),
 *   'primary key' => array('bar')
 * );
 * @endcode
 * and you want to change foo.bar to be type serial, leaving it as the primary
 * key. The correct sequence is:
 * @code
 * $schema = \Drupal::database()->schema();
 * $schema->dropPrimaryKey('foo');
 * $schema->changeField('foo', 'bar', 'bar',
 *   array('type' => 'serial', 'not null' => TRUE),
 *   array('primary key' => array('bar')));
 * @endcode
 *
 * The reasons for this are due to the different database engines:
 *
 * On PostgreSQL, changing a field definition involves adding a new field and
 * dropping an old one which causes any indices, primary keys and sequences
 * (from serial-type fields) that use the changed field to be dropped.
 *
 * On MySQL, all type 'serial' fields must be part of at least one key or index
 * as soon as they are created. You cannot use
 * \Drupal::database()->schema()->add{PrimaryKey,UniqueKey,Index}() for this
 * purpose because the ALTER TABLE command will fail to add the column without
 * a key or index specification. The solution is to use the optional $keys_new
 * argument to create the key or index at the same time as field.
 *
 * You could use
 * \Drupal::database()->schema()->add{PrimaryKey,UniqueKey,Index}() in all
 * cases unless you are converting a field to be type serial. You can use the
 * $keys_new argument in all cases.
 *
 * @param $table
 *   Name of the table.
 * @param $field
