Gets the schema definition of a table, or the whole database schema.
The returned schema will include any modifications made by any module that implements hook_schema_alter().
string $table: The name of the table. If not given, the schema of all tables is returned.
bool $rebuild: If TRUE, the schema will be rebuilt instead of retrieved from the cache.

}
if (!isset($table)) {
return $schema;
}
if (isset($schema[$table])) {
