I think we just don't need to add the special timeout kind to the
core.  postgres_fdw can use USER_TIMEOUT and it would be suffiction to
keep running health checking regardless of transaction state then fire
query cancel if disconnection happens. As I said in the previous main,
possible extra query cancel woud be safe.
