Hi,

I've already implemented preserving PG_PROC oids during pg_upgrade
in a way like relfilenodes, etc, actually, it is quite simple, and on the first
look there are no any problems.

About using surrogate key - this feature is more for data generated by
the DBMS itself, i.e. data processed by some extension and saved
and re-processed automatically or by user's request, but without bothering
user with these internal keys.

The main question - maybe, are there pitfalls of which I am not aware of?

Thanks for your replies!
