No. It's a security precaution.

That probably means you have some user-defined functions that are
not sufficiently careful about search_path. You want to either
schema-qualify every reference in the function body, or attach a
"SET search_path" clause to remove the function's context dependency.
(If you're using SQL-language functions in v14 or later, another
option is to use the SQL-standard syntax instead of writing the
body as a string literal. Then the object references in the function
are parsed at definition time.)
