It used to be that the oid columns of the system tables were hidden (hardcoded, as far as I know), but as of Postgres 12 I believe there are no more hidden columns: SELECT * from a table always gives all the columns. I think a "select all columns except …" would be more useful; or another approach would be to use a display tool that defaults to displaying only a portion of large fields.
