Hm. In the old code it was basically a chance artifact that this example
happens to produce the "right" width estimate.
Hello,
While working on adapting the Multicorn FDW for 9.6, I noticed that there is a
regression with regards to estimating the remote relation width.
This behavior can be exposed using the postgres_fdw, using
"use_remote_estimate".
Test case:
CREATE EXTENSION postgres_fdw;
CREATE SERVER loc
