@RuslanOm Can you change the issue title so that developer can see what's the problem without looking into the issue content? Issue titles should be self-describing whenever possible.

According to the ss_postgres_loader.py code and specific line it was fixed in b63b44c. Closing as obsolete. Works well in the build version 0.16.1052 built on 2021-07-19.
