I have a small table of wells with just a name, lat, lon, and geometry in an Esri Shapefile. I am putting them into a PostGIS database and it works well, so I added an arbitrary well_id as a serial so they'd have a unique numeric id for the Primary Key.

The picture here works, but the well_id attribute is red, and I'm not sure why, or if there is a way in FME to make it not red.

Did I set this up wrong or is this expected behavior in FME when adding a serial that is not in the source shapefile and going to PostGIS?

You have not done anything wrong. This means that FME does not know where to get the data from and save it into that attribute. If you do know however, you could just connect the attribute manually by dragging or creating a new connector from the source data into that writer, or simply renaming the attribute in the writer to match the original attribute name in the reader.

Alternatively, you could use the "Automatic" or "Dynamic" options to get the attribute name updated automatically.

In the example below, the original data are in a different language than the destination data.

Just drag a connector as shown below:

The red color will be gone:

Other options will be to use the AttributeManager or AttributeRenamer transformers to rename the attribute names
