I'd prefer if it was separate since we want to minimize the number of 
multi-statement TOC entries...I think. A new TOC entry is close to zero 
cost. Reformatting the TOC to include the tablespace name is more 
expensive, but there are a few things I'd like to add, so it's worth it.


>If the SET fails, what tablespace is expected to be chose?

Good question. Is there a name for the normal/default/whatever tablespace? 
Tom may need to implement:
    SET DEFAULT TABLESPACE AS FRED    SET DEFAULT TABLESPACE DEFAULT

or something less tacky, but allowing for the default to be derived from 
the schema & database rather than the last SET command. The pg_dump will 
need to check the result of the SET command and reset the tablespace if it 
fails...and probably die if that fails.

I'm happy to do the pg_dump changes, assuming Tom gets the SET stuff sorted 
out. But would appreciate it if you could do some testing.
