I think the issue is the license term, not the copyright. In my
opinion, we could live with copyrights other than ours as long as
their licenses are as free as the PostgreSQL license.

This looks safe for me.

Seems bad for us, since they are GPL'd...

Looks good. Its licence is BSD.

Not sure about above.

Nothing is mentioned about the license. We could ask the author about
it.

Seems ok for me.

Also good.

This indicates it's safe?

License term seems ok for us.

I think he could leave his copyright, but it is up to him...

I contacted the author when I borrowed his code. At that time its
license seemed to be sort of "public domain." But today I found on his
web page (http://www.ff.iij4u.or.jp/~nrt/lv/) that he seems changed
the license to GPL2. This is bad news for me, so I have written to him
about it and am waiting for his reply...
