Parameters

$table: Name of the table to be altered.

$fields: Array of fields for the primary key.

Deprecated

as of Drupal 8.0.x, will be removed in Drupal 9.0.0. Instead, get a database connection injected into your service from the container, get its schema driver, and call addPrimaryKey() on it. E.g. $injected_database->schema()->addPrimaryKey($table, $fields);
