One other point that could be made here is that it's not going to
surprise anybody that access to a remote table is really slow compared
to access to a local table. Why would it surprise anybody if planning
for a remote table is really slow compared to planning for a local
table? Where is the evidence that anyone would even *notice* the extra
planning time, compared to the execution time of the finished query?
This is still all about premature optimization.
