   @yevgenypats So, looking at your example, the panic is coming because you only add a null to *one* of the fields in the record builder. Which means the builders are unbalanced for the record. One column has a length of 1 and the rest all have length 0, and a record must have the same number of rows in every column. So that's where your panic is coming from.
   
   That said, after changing your example so that it appends a null to *every* column, I still got an error from a nil pointer dereference so I'm looking into that to fix it.
