I'm sure there's things we can do to improve the performance of the FDW.
Not sure we'll get to a point where we are actually cacheing information
from the far side... but who knows, maybe if we arrange to have a
notification sent whenever certain objects are updated...

These things could be worked on independnetly, of course, no need to
have one done before the other.
