I think maybe Michael missed this message (?)
I had applied some changes on top of Peter's patch.

I squished those commits now, and also handled ClusterOption and VacuumOption
in the same style.

Some more thoughts:
 - should the structures be named in plural ? "ReindexOptions" etc.  Since they
   define *all* the options, not just a single bit.
 - For vacuum, do we even need a separate structure, or should the members be
   directly within VacuumParams ?  It's a bit odd to write
   params.options.verbose.  Especially since there's also ternary options which
   are directly within params.
 - Then, for cluster, I think it should be called ClusterParams, and eventually
   include the tablespaceOid, like what we're doing for Reindex.

I am awaiting feedback on these before going further since I've done too much
rebasing with these ideas going back and forth and back.
