OK. I'm try to explain my problems. My customer have Postgre server with any older version of my DB (without any new or modified views, functions etc.) and when i create export (in pgAdmin3), then pg_dump makes a SQL script. Ok. It's nice, but when i'm trying to run this script on customer's machine, then i have many errors, because any views are not in his database, and script trying to drop it. When i'm set to don't make drop functions (in export), then i have other errors, with existing views (view allready exists). Petr
