They want synonyms for functions, but as far as I can see the same can be
achieved with minimal extra work by creating a new LANGUAGE SQL function 
that calls the original.
CREATE FUNCTION newschema.newname( atype ... ) RETURNS rtype 
AS ' select oldschema.oldname ( $1 ... ) ' LANGUAGE SQL;
with apropriare values for the lowercase bits and elipsis.
