To refresh people's memory I have a simple Delphi interface (TEdit and
TNavigator) connected via ODBC to a Postgresql 8.0 table.

I've tried the earlier suggestions in various forms with no success.

I again was successful in updating the table with the table containing no
serial column. With the serial column included I get an error massage that
the serial column needs a value.

I don't understand why the serial column is generated when a row is created
manually through Postgresql Admin interface but it doesn't generate when a
row is added through the Delphi interface.

Could someone explain this difference?
