I think the problem is that the first time the function is called, it is
compiled and cached for later use. At that time the function is bound
to the table oid, so even though you change the search path, the cached
copy still calls the old table.
If you exit psql and re-enter, or change the schema _before_ you call
the function for the first time, it should be fine.
This highlights another problem with our plpgsql function caching.
