When using arrays in Postgres, the default HTML report does not show this. E.g. a column defined as text (Type: Text, Is Array Type: true) is only shown as “Text” in the ER diagram and also as “Text” in the Entities list. There is no indication at all that the column is an array.
It would also be nice if that was shown in the WorkSpace as well, e.g. as Text instead of just Text
