At first glance,
I think it might be easy to send to back-end the first INSERT statement if you get a blank for the form
and the second one if you don't get a blank...  With an if statement , for ex

Why can't you do that?
Maybe I am misunderstanding your situation.

  Hi guys, 

  I have a little problem.
  I want to insert a blank on a varchar field. When i do the follow :
    INSERT INTO "Seller"("name", "id")VALUES ( null ,'1'); it works perfectly !!!
  But if i try :
    INSERT INTO "Seller"("name", "id")VALUES ( '','1'); The postgres insert in my database the value '', and i dont want it.

  The first way, is the only way for insert blank values !? Because it is not good for me, because i received a lot of fields from a form and i don't want to put null if the value is blank, and don't if it is not blank.
