I use FME 2020.1.3.

What I want to do is to use a FeatureReader to read a PostGIS DB depending on created attributes ( usual generic approach) and to write them to an other PostGIS DB with an FeatureWriter, using Published Parameters to define the destination. As I use the generic port as outpur from the FeatureReader, the data loses its data-type information. I know, that those informations are given through the Schema port of the FeatureReader and that there is a way to merge them again to the data.

I found serveral post about this topic (

Unfortunatly, I don't understand how to do it in my case.

The pictures shows, what I have done so far.

Additionally, I expose the attribute read by the FeatureReader inside it, I dont know if that's right. What do I need to expose where and when?

Thank you in advance for any guidance in this topic!
