As Dilip said, we need to unregister sync requests for files that got successfully copied to the target database, but the overall alter database statement failed. We are doing this when the database is created successfully, but not when it fails.

Correct, I have done this cleanup, apart from this we have dropped the
fsyc request in create database failure case as well and also need to
drop buffer in error case of creatdb as well as movedb.  I have also
fixed the other issue for which you gave the patch (a bit differently)
basically, in case of movedb the source and destination dboid are same
so we don't need an additional parameter and also readjusted the
conditions to avoid nested if.
