How do I adjust the table link endpoint in PgAdmin's ERD tool after autogenerating it from an existing database?

I can move the lines themselves around, but I can't move the endpoints, which cause the lines to overlap. The only way to understand which relationship is being referenced is by hovering over the connection. A printout of a complex ERD becomes unusable.

I can move the tables and the lines themselves, but cannot move the endpoints.

In version 6.10, one action that seems to help is to drag one segment parallel towards another and beyond, this automatically erases the extra perpendicular segment. It works by dragging only one of the segments and not the other (apparently the one closer to the table). See attached images for clarification.
