Certainly you can invent scenarios where letting the search path vary
from call to call is useful, but the question is which behavior is
*more* useful. I think it's becoming clear that having a predictable
search path is usually what a function author will want.
It would probably be a good idea to allow the function's search path to
be explicitly specified as a clause of CREATE FUNCTION (otherwise it
will be a headache for pg_dump). So we could allow both viewpoints,
if there is a way to explicitly say "don't force any search path".
Perhaps specifying an empty path could mean that. But I think the
default should be to adopt the current search path (at the time of
CREATE FUNCTION) as the function's permanent path.
