I'm wondering what is the problem in placing the old/original name
after the "pg.dropped" prefix. I know that the tuple in pg_attribute
is temporary, but what are the possible conflicts the comment talks
about?


May be when a column with the same name is added and again dropped ? Of course, we can have the attribute number and column name both to avoid conflict.

Thanks,
Pavan
