DROP ROLE dependency tracking ...

good morning,

some days ago i have fallen over an issue which feels more or less like 
a bug. consider:


test=# create role xy LOGIN;
CREATE ROLE

test=# grant connect on database test to xy;
GRANT

test=# drop role xy;
ERROR:  role "xy" cannot be dropped because some objects depend on it
DETAIL:  access to database test

this is a totally fresh instance --- all i did was creating a db called 
"test".
failing would make sense if i would the owner of an object but i fact i 
don't own anything.

test=# SELECT version();                                                
version                                                 
----------------------------------------------------------------------------------------------------------PostgreSQL
8.4develon x86_64-unknown-linux-gnu, compiled by GCC gcc 
 
(GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7)
(1 row)

is this a known issue?
   many thanks,
      hans
