Re: Insert 'NULL' value in Postgres with Nim 0.19.1 without 'nil'

[ThomasTJdev]

Thank you for the explanation @mikra. I do agree that a proper binding would be 
the best solution. My SQL builder does only substitute with `NULL` values, so I 
don't see, that I would encounter problems with `IndexError` any different than 
on 0.18.0?
