> I've found some minor issues in "show tables" command:
> 1. In the SessionCatalog.scala, listTables(db: String) method will call listTables(formatDatabaseName(db), "*") to list all the tables for certain db, but in the method listTables(db: String, pattern: String), this db name is formatted once more. So I think we should remove formatDatabaseName() in the caller.
> 2. I suggest to add sort to listTables(db: String) in InMemoryCatalog.scala, just like listDatabases().
> I will make a PR shortly.
