Re: BUG #8291: postgres_fdw does not re-read USER MAPING after change.

I realized that postgres_fdw is caching the connection, but when you have e=
xisting items that use the same USER MAPPING and do not cache it such as db=
link you get inconsistency in implementation and this should be avoided.

Hmm i don't think that's a bug. It's because the postgres_fdw caches the co=
nnection within your local session, reusing it for any subsequent foreign t=
able access.
