Well, being able to switch to a different conversion is fine, but I don't
think that's a good argument for tying it to the schema search path.
What would make more sense to me is a command specifically setting the
conversion to use --- perhaps a GUC variable, since then ALTER USER SET
and ALTER DATABASE SET would provide convenient ways of controlling it.
