The patch does several things:

Browse Source 
It adds a WITH OIDS option to the copy command, which allows
dumping and loading of oids.

        If a copy command tried to load in an oid that is greater than
its current system max oid, the system max oid is incremented.  No
checking is done to see if other backends are running and have cached
oids.

        pg_dump as its first step when using the -o (oid) option, will
copy in a dummy row to set the system max oid value so as rows are
loaded in, they are certain to be lower than the system oid.

        pg_dump now creates indexes at the end to speed loading
