The current behavior of SHOW TABLES displays both tables and views from INFORMATION_SCHEMA.TABLES. To match this behavior, synonyms are also displayed. If necessary, we may adopt the SHOW FULL TABLE syntax from MySQL.

spanner> SHOW TABLES;
+----------------------+
| Tables_in_example-db |
+----------------------+
| Album                |    # Synonym
| AlbumDetails         |    # Renamed table
+----------------------+
2 rows in set (0.02 sec)
