Hi everybody! Is this a bug?: When I'm executing this (see below) query I have unexpected backend closing. When I will remove last line with "AND user_database.status_id = 'A'" - - it's working OK. But there are not a lot of conditions! Do anybody know about this problem? If it was discussed before - can you tell me where I need to look for the answer? I'm working with PostgreSQL two months only and I like it - nice perfomance, cool ideas (temporary and inheritanced tables,...), and I don't want to replace it. Thank you!
