Here I attached a patches that are rebased to the latest master.

Apart from rebase, I have added the support for external relation to be
stored in the
pg_class. These are additional relations that may be used by the

these relations cannot be queried from SQL statements and also these
relations cannot
be dumped using pg_dump. Yet to check and confirm the pg_upgrade of these

JIT doesn't work at yet with these patches.
