Yes, it allows me to work around a conflict in my application by  
deciding to schema-qualify use of a one of the two conflicting  
extensions. It's a way I can quickly work around the issue. Not ideal,  
I grant you, but I don't see us getting into the business of setting  
up a registry requiring uniqueness. Besides, some extensions, like  
pgTAP, pretty much scream for a schema of their own completely  
independent of everything else. I want the option to be able to do  
that when appropriate. I don't think I'd ever put each module in its  
own schema, FWIW.

Best,
