Hmmmm. I don't see any reason why this couldn't be set by any user at
runtime, really. From a security standpoint, it's less of a risk than
search_path, and we allow anyone to mess with that. Then we'd have the
simple factor of setting it in postgresql.conf or setting it in the
function definitions via WITH.
