Thread: Re: Null boolean values show as false in the data

While your at it null values need to be treated correctly for other field 
types.

I don't think "" = <null> in Postgres.  If so then it would be nice to be 
able to set text/varchar to null somehow.

Ben

NULL *is* handled for text. An empty field is handled as NULL, an empty 
string must be entered ''. This is documented.
