Attachments

I broke this up into several small patches.  Notable changes are as
follows:

* Adjusted to the tab completion code to work more like the VACUUM utility
  options.

* Introduced a new ExecCheckpoint() function in checkpointer.c and moved
  the privilege check and options parsing there.

* Removed the notes in the docs about when to use the CHECKPOINT command.
  I'm not opposed to adding something like that (in fact, I think it's a
  good idea), but IMHO we should bikeshed on that separately, maybe even in
  a new thread.

Thoughts?
