I was surprized that few people really want DDL commands inside transactions.
Are there any reasons to releasing lock before end of transaction except
that long term lock for system tuples is not preferable ?

I think that UnlockRelation() is unnecessary fundamentally.
Mine is the simplest way to achieve this.
If there's no problem,I am glad to remove UnlockRelation() calls.
