Ewe. There would no longer be a guaranteed name for the serial column
sequence. Of course, pg_depend has the information, but how do you get
at that when you create the dump file, and be _sure_ you are going to
hit the right name, especially if you restore only part of the dump.
Seems this kills the idea of this patch. With 64-byte names, let's see
if we still get complaints about name conflicts.
