The database manager could only show one table at a time, so nothing in it answered "how do these tables relate". This adds a Diagram mode beside the data view, for PostgreSQL: the tree's checkboxes pick the tables, and the canvas draws them as cards on a pan/zoom surface. There are deliberately no edges. A schema of any size turns an edge-drawn ERD into a hairball, so the relationships surface on hover instead: hovering a table lights every table it is linked to and the columns tying them together, hovering a column lights only the column it is actually paired with. Only the connected database can be drawn, so another data table's rows in the tree get no checkbox in this mode, and a row of the connected one toggles what is drawn rather than selecting it for a data pane that is not shown. Foreign keys come from a new ALL_FOREIGN_KEYS marker that reads the whole database in one query. The existing FOREIGN_KEYS marker is per table, which would be one job per card. It reads pg_constraint rather than information_schema, whose constraint_column_usage loses which column of a composite key pairs with which.
