PostgreSQL version: 8.0.3 Windows
Operating system: Windows XP
Description: PostgreSQL oledb driver
Details:

When checking values of boolean fields through the driver, I get incorrect
results (Inconsistant).

Also when I try updating a boolean field I get an error saying "No columns
defined in rowset" but works fine using query tool in pgadmin III.

I am using Delphi with ADO datasets connecting with the PostgreSQL oledb
driver.
