Interesting... and thank you!
While I did expect to see tableoid, cmax, xmax, cmin, xmin and ctid in my
tables... I never expected turning on "Show system objects" would show
sequences and tables as Postgres Types.

So I am knowledgeable, can you explain why that happens?

In Postgres, the row schema of objects in pg_class (tables, sequences, views etc) is also a "row-type". Effectively, a composite type that can represent a row in a class: https://www.postgresql.org/docs/10/static/plpgsql-declarations.html#PLPGSQL-DECLARATION-ROWTYPES
