I'm using pgAdmin4 on Linux, but for some reason I'm not able to list my stored connections anymore. It worked on a fresh install for a few days and then suddenly stopped working after a reboot (no installations/updates done beforehand). I experienced this on multiple machines with similar setups.
System info:
When I try to list my stored connections, the following appears in ~/.pgadmin/pgadmin4.log:
Traceback (most recent call last):

ores = OrderedDict(self.orig_col._asdict())
AttributeError: 'psycopg2.extensions.Column' object has no attribute '_asdict'
Any ideas what could be wrong here?
This was a bug due to new release of psycopg2 module, It has been fixed with latest release of pgAdmin4 v4.5, Please upgrade it to latest version.
