Applied with minor revisions.  I noticed while testing this that
although you fixed it for the case of the user having unnecessarily
quoted the preceding name, for example given a table foo,

    update "foo" set <tab>

it's still not bright about letting you complete such an entry in the
first place -- try

    update "f<tab>

That doesn't invalidate this patch, but there's still more work to do
on the completion queries.
