I have implemented the patch with approach2 as well, i.e. instead of
scanning the pg-class, we scan the directory.

IMHO, we have already discussed most of the advantages and
disadvantages of both approaches so I don't want to mention those
again. But I have noticed one more issue with the approach2,
basically, if we scan the directory then we don't have any way to
identify the relation-OID and that is required in order to acquire the
relation lock before copying it, right?

Patch details:
0001 to 0006 implements an approach1
0007 removes the code of pg_class scanning and adds the directory scan.
