Internal Server Error after psycopg2 upgrade

Hello everybody,

I'm on ArchLinux with pgAdmin 4.4:

Python Version
3.7.3 (default, Mar 26 2019, 21:43:19) [GCC 8.2.1 20181127]
Flask Version
1.0.2
Application Mode
Desktop

since I've upgrade python-psycopg2 from 2.7.7-1 to 2.8.1-1,
I get a popup "INTERNAL SERVER ERROR" with the message:
'psycopg2.extensions.Column' object has no attribute '_asdict'
when I want to expand a server in my "Servers" list.

I hope this is the right place to report this.


Kind regards
Benjamin
