BUG WITH CREATE FUNCTION.......

Hi,

My pgsql an postgres ( version V 7.0.2 ) stop with an error when i write 
the following query under pgsql :
create function test(text) returns text AS '' LANGUAGE 'sql';

ERROR under pgsql :

pqReadData() -- backend closed the channel unexpectedly.       This probably means the backend terminated abnormally
  before or while processing the request.
 
The connection to the server was lost. Attempting reset: Failed.


Error under postmaster :

ERROR:  ProcedureCreate: procedure toto already exists with same arguments
