> Excessive exclusive lock used in some DDLs with DummyTxnManager

> In DummyTxnManager, the lockMode for a WriteEntity (e.g. database, table) is
> determined by "complete" instead of its writeType. But since DDL output
> WriteEntity is usually complete, some DDL operations might be given exclusive
> locks which are actually not needed, which causes unnecessary locking
> contention. For example, in createTable, DummyTxnManager suggests an
> exclusive lock to table database writeentity since it is complete.
