OK, committed. I also committed the 0002 patch with some wordsmithing,
and I removed a < 0 test an an unsigned value because my compiler
complained about it. 0001 turned out to make headerscheck sad, so I
just pushed a fix for that, too.

I'm not too sure about 0003. I think if we need an is_shared flag
maybe we might as well just pass the tablespace OID. The is_shared
flag seems to just make things a bit complicated for the callers for
no real benefit.
