Our usual practice is to write the copyright like it is in partition.c
even in new files. This avoids any question about whether any of the
code was copied-and-pasted from somewhere else in PG. Even if not one
word in the file can be traced to code that was somewhere else before,
it seems to me that this is an appropriate thing to do, to give due
credit to those who came before us.
In short: we should make partition.h's copyright look like partition.c's
not vice versa.
