Hi,

i created a stored procedure (function) under postgreSQL and when i checked deeper into my DB, this is what i get:
....
    END;
$BODY$
  LANGUAGE 'plpgsql' VOLATILE
  COST 100;
ALTER FUNCTION myschema.get_count_languages(character varying) OWNER TO myuser;

to what corresponds the parameter COST 100 ?
it is the first time i see that :-(
thx.
