I tried this and it doesn't actually do any good.  Patch attached, which
I intend to throw away.  The main problem is that most files interested
in analyze stuff also wants to do vacuum_delay_point, or access
default_statistics_target, both of which are declared in vacuum.h, so
these files have to include vacuum.h anyway. 

In order to achieve anything worthwhile we'd have to do a three-way
split I think, and that's more trouble that this is worth.
