Re: bug fix and documentation improvement about vacuumdb

I agree.  Supporting pattern matching should, if anyone is interested in
trying, be done separately in its own thread, no need to move the goalposts
here. Sorry if I made it sound like so upthread.

When sending an update, please include the previous patch as well with your new
tests as a 0002 patch in a patchset.  The CFBot can only apply and build/test
patches when the entire patchset is attached to the email.  The below
testresults indicate that the patch failed the new tests (which in a way is
good since without the fix the tests *should* fail), since the fix patch was
not applied:
