Okay, after further reading, looks like this could be a bug:
"PsqlCommandBuilder Object: Gets the automatically generated PsqlCommand object required to perform updates on the database when an application calls Update on the PsqlDataAdapter." -- Pervasive ADO.NET provider docs.
Key words are "automatically generated" as I would expect from an ADO.NET Provider. Looks like any communication with support costs $250US. Anyone know if this fee is waived for bugs?
TIA,
