[pgadmin-support] No SQL errors visible in pgAdmin 4 1.5

When I run an incorrect SQL I cannot see SQL error messages in pgAdmin 4 1.5. However, when the same SQL is run on the same database from pgAdmin III 1.22.2 I can see a full error message telling me what was wrong (please see the screenshots). It looks to me like the messages are turned off somewhere but I cannot see it in any preferences or options. I would appreciate any help or hints how to turn them on or where I can see them in pgAdmin 4 1.5.

I am using PostgreSQl 9.6 on Windows 10 Pro.

Thank you and kind regards

Pawel
