renaming a DB through UI?

How is one (or is one) supposed to rename a DB through the pgAdmin UI?
In 1.4.2 in the DB properties dialog the OK button becomes enabled if
you changed the name in the dialog, but you get an error about renaming
the current DB (there does not seem to be a way to not have that DB be
your current DB). In 1.6 RC1, typing in a new name in the dialog does
not enable the OK button and does not add the alter SQL to the SQL tab.
I am wondering if this was a response to the 1.4.2 problem or if a bug.
If it is a conscious change then graying the field out (as is done with
the OID, tablespace, etc. fields) might be more appropriate otherwise
the user is given mixed signals--he/she makes a change and nothing
happens in response... And of course the big question is whether
renaming through the UI should be supported.
