Dear David,

Thanks!
While checking more, I was surprised because I found many files which do not
have Copyright via " grep -Lr Copyright --exclude-dir .git ..." command.
I'm not sure whether it is expected, but all sql files in src/test/regress/sql and
many files in contrib do not have. Do you know something about it?

Sorry, I'm not sure about it. Before submitting a patch I have checked the
manual that "PostgreSQL Coding Conventions", but I could not find any.

There seems a tendency that Copyright for recently added files have added it to
the very beginning, but I can suspect from the result that there are no specific
rules about it.
```
$ grep -rn Copyright --include="*.pl" | awk -F ':' {'print $2'} | sort -nr | uniq -c
