Azure Data Factory: Which Version of npgsql is used?

Question

As far as I understand, the Azure Datafactory V2 uses the .NET framework "npgsql" to copy data from or to a PostgreSQL database.
Currently, I am having issues with some data types in the PostgreSQL database I want to copy data from. With the newer versions of npgsql, it should be possible to read these data types. Hence the question:
What version of npgsql does the Azure Data Factory V2 use?
Is it possible to check the version of npgsql?

I don't know if this helps, but I am using a Self Hosted Runtime Environment version 5.1.7655.1

Answer 1

We can conclude that:

1. According to the ADF V1 documentation , the built-in driver version is between 2.0.12 and 3.1.9.
2. According to the ADF V2 documentation , the driver starting from version 3.7. It seems that we cannot manually specify the version number.
   Kindly let me know if you need more information.
