Unable to update Domain properly

Hi,

While updating Domain from pgAdmin-III  , I observed an error.

When I update only Domain name it is working properly, but when I try to update multiple fields, I get an error.

For example,  if I try to rename Domain TestDomain to TestDomain1 and also modifies one or more fields (except comment). I get below error.

ERROR:  type "pem.TestDomain" does not exist

Generated SQL:

ALTER DOMAIN pem."TestDomain"
  RENAME TO "TestDomain1";
ALTER DOMAIN pem."TestDomain"
  DROP NOT NULL;

Thanks,

Khushboo
