Well, it does do that, at least for the part of the query that will be
executed on the remote server. But if you read it to mean the whole
query would be EXPLAINed on the remote server, that's wrong.

The objection I have to "use_remote_explain" is that it's focusing too
much on the mechanism (ie, send an EXPLAIN command for execution) rather
than the result (ie, get a cost estimate from the remote server).
So I'm inclined to change the code to match the docs rather than vice
versa. Anyone have a contrary opinion?
