Hi Ritesh,
NORMA generates Domains automatically when needed, but often inlines the domain definitions (same information without a domain name). What is your scenario for requiring explicit domains?
There is no installed mechanism for generating multiple schema names right now, but I posted a mechanism for using custom properties to modify the generated schemas in SQL server. It should work with Postgres as well. Download the zip from http://www.ormfoundation.org/forums/p/573/1698.aspx#1698 and follow the instructions there. [see below for possible required modifications on the installer.] A quick test indicates that the generated PostgreSQL DDL includes the custom schema name and looks reasonable, but I haven't tested by loading it into a Postgres DB.
Let me know if this works for your system, and I can repost the transform with updated installers (to handle VS2010 and 64-bit systems).

(Possible modifications to installer)
The installers in the linked zip do not have a VS2010 installer, but a 2010 installer is easily created (replace the two occurrences of 2005 with 2010). The more subtle issue occurs on a 64-bit system. Visual Studio is a 32-bit application and is installed in a different location in the registry. You'll need to modify HKLM\Software\ to HKLM\Software\Wow6432Node\ to successfully install on a 64-bit system.
