Renamed tablespace not shown for DB until reconnect

I created a tablespace, then created a database using this tablespace as 
a default.  Then using the latest version of PgAdmin III 1.6.1, I 
clicked on the tablespace name, and using Properties I changed the 
tablespace name.  Upon clicking Ok, the new name is shown for that 
tablespace in the tablespace list.  However, if I click on the database 
name, it continues to show the old tablespace name.  I tried doing a 
refresh on that database name; nothing changed.

I then disconnected and reconnected.  Now, the database is showing the 
new tablespace name.  Is this working as designed?  It is misleading to 
the user; I at first thought that PG itself had a bug in that it 
continued to associate the old, non-existent tablespace name with the 
database.
