Select from sqlite to postgres via virtualpg converts null ints to zeros

[Brent Wood]

HI,

I'm inserting data to a table in postgres from a table in sqlite via virtualpg.

Where an int column has a null value in Sqlite, it is converted to a zero in the Postgres column.

This does not seem to happen with char/varchar columns (so far).

Is there any (simple) way to change this behaviour? 

Should I file a bug report?
