The views do not need this sort of change, because they're parsed
only once during initdb.
The bodies of functions in information_schema do need qualification,

looked through them for the issue in the past.

I think that ship sailed long ago. It might be workable to attach
"SET search_path" clauses to the functions, if you want to make them
more bulletproof.
