It might also be useful to allow something such as PATH CURRENT to
attach the current schema as the search path for all calls of that
function.
This would be useful because then SQL scripts for installing 3rd party
modules could install nicely into any schema by merely setting
search_path before running the script.
For instance, PostGIS doesn't support installing into a schema other
than "public" because they want to have a static SQL install script
rather than generate one based on your desired search path.
