Questions about Fill, Serial, Update, Delete

[CNPSV]

I am interesting in buying PostgreSQLDirect for .net but I have some questions:
- if I have a field of type "serial" why doesn't the direct connector recognize the field as Serial.
- if I have a dataGridView, how can I autoFill and autoUpdate, from the designer
- if I have in postgreSql a not null field, why can I enter a new field with a null value and no message or exception is shown / thrown.

Maybe I am doing something wrong with the wizard, that's why I am looking for some simple tutorials.

Serial its just an integer type with sequence. That's why we map it to System.Int.

You need to use "With refresh SQL" option when configuring PgSQlDataTable comtrol.

- if I have in postgreSql a not null field, why can I enter a new field with a null value and no message or exception is shown / thrown.
