Imho the system schemas should be included, because they don't hurt.
If you do tab completion, you'll usually enter a few chars and hit
<tab>, so you won't get confused by pg_catalog and information_schema
just because you won't see them. Also, it makes sense to explicitely
put pg_catalog at the beginning or the end of search_path, so tab
completion should support that.
I would opt to exclude pg_temp_*, though - these don't serve any
purpose SQL-wise and the name changes all the time anyway.
