Would the above changes work?

Hi Richard,
Your changes works ! But now I know what mistake I did:
The error is occurring because I'm doing a CREATE OR REPLACE VIEW command.
The command with null:character(3) works too.
The error is because I create a view then try to change the definition
with the CREATE OR REPLACE VIEW command
When I drop the view first , and then create again the view (in a
separated transaction), now the command works! (this is a bug?)
I'm using a postgres 8.2.4 on Linux.
Thanks a lot!
