I am reading from a postgresql database. Attribute [publication_time] has a primary key and type timestamp. In the postgresql database this attribute has values, but FME 2018.1 inspector shows no (blank) values.
Can timestamp as primarykey be the cause?
Kind regards

I know it doesn't answer your question, but I would argue that for almost all use cases it's not a great idea to use a timestamp as a primary key.

For efficiency and ease of use, it's difficult to beat an integer primary key generated from a sequence defined in your database. If you dabble with synchronization or distributed datasets, I would recommend using a GUID primary key.
It seems that the problem is caused by the potgresql database. There is a combined primarykey of 2 attributes. Can FME solve that problem?
Kind regards
