Psqlodbc 7.1.11

Hi, with psqlodbc 7.1.9 an attempt to write to a table that the current user
doesn't have enought privilege raise error
number -2147467259 and err.description contains "Permission denied", with
psqlodbc 7.1.11 it raise the same err number
but text has changed to "Error while executing the query", that is less
descriptive and I need a descriptive text because error number
-2147467259  is raised for various errors (emty row, referential integrity
violation, duplicate key ...) .

Is this a bug ? How can I know the correct error ?

Thanks
