Keep in mind that you can't do that in released versions (8.1 and
earlier); it's only possible in the current development branch.  If you
are using 8.2dev, see the code comment -- it's explained there.

Hi,
  Thanks for replying. I am using the latest code that is 8.1.2. I look at the comments of construct_md_array function. On it, it says that NULL values are not supported. Please kindly help me out or tell me some other way.
                                                          Thankyou.

Hello

there isn't other way :-). If you can, use source code from cvs and compile 
postgresql.

or you can use string array, and fictive NULL values.
