Bug - SQL can not be generated for Login Roles

To Whom it may concern,

BUG REQUEST:

I am trying to generate the DDL of a login role by clicking on the login role in the pgAdmin tool. In pgAdmin 3 it works and generates the DDL, but in pgAdmin 4 It just hangs and you get Connection to the server has been lost. I have a high number of Login/Group Roles (over 700+ login roles) and I would like to get the DDL for any login user I select. I think the query behind the scenes cannot handle the volume of login roles, and it's similar to a Cartesian product with the query it uses.

ENHANCEMENT REQUEST
Also, if possible I would like the following enhancements to this pgAdmin 4 Tool. I would like to have a compare tool incorporated into this utility. I would like to be able to compare databases/schemas between other databases/schemas and for it to generate a fixit script that would have all the sql to make either the source / target the same. (like a diff)
