alvherre=# create function anyelem2 (anyelement) returns int language plpgsql
as $$ begin return 1; end $$;
CREATE FUNCTION
alvherre=# select anyelem2(textout('oh'));
ERROR: PL/pgSQL functions cannot accept type cstring
CONTEXTO: compilation of PL/pgSQL function "anyelem2" near line 0

noticed that before).
