Hi Burak. I have been testing ingestr using a source and destination Postgres database. What I'm trying to do is copy data from my Prod database to my test database. I find when using replace I get additional dlt columns added to the tables as hints. It also does not work for a defined primary key only natural keys. Composite keys do not work. Can you tell me the basic, minimal that it supports. I would love to use it to keep our Prod and Test databases in sync, but it appears that the functionality I need is not there. Thanks very much.
