I think there is a pretty strong practical argument for excluding the
pg_temp and pg_toast schemas from completion for search_path, namely
that when does anyone ever need to include those in their search_path
explicitly?
The use-case for including pg_catalog in your path is perhaps a bit
greater, but not by much.
I'm not sure that what we do when auto-completing after FROM is an
entirely valid analogy, because the use-cases are different as a result
of the rules about schemas getting automatically included in your path.
