My original read of the problem determined (for me personally) that the only way one could be in violation of copyright was if the data was incorrect (i.e. not factual). It presented an interesting contradiction. The only way they could sue is by agreeing that their data is faulty and should not be trusted. :-)

The case Merlin refers to below seemed to rule that even faulty information is not a concern.

Personally, I think the best choice is to officially state a position on the matter and agree to remove any copyrighted material that has been used without the permission of the copyright owner from PostgreSQL if or when this is ever demonstrated in court. Until that time, the damage to the community by responding to this unproven legal threat would be unreasonable to bear.

The one interesting case that I can recall were this was tested was
this (lifted from Wikipedia):

In October 1984, Fred L. Worth, author of The Trivia Encyclopedia,
Super Trivia, and Super Trivia II, filed a $300 million lawsuit
against the distributors of Trivial Pursuit. He claimed that more than
a quarter of the questions in the game's Genus Edition had been taken
from his books, even to the point of reproducing typographical errors
and deliberately placed misinformation. One of the questions in
Trivial Pursuit was "What was Columbo's first name?" with the answer
"Philip". That information had been fabricated to catch anyone who
might try to violate his copyright.[5]
The inventors of Trivial Pursuit acknowledged that Worth's books were
among their sources, but argued that this was not improper and that
facts are not protected by copyright. The district court judge agreed,
ruling in favor of the Trivial Pursuit inventors. The decision was
appealed, and in September 1987 the United States Court of Appeals for
the Ninth Circuit upheld the ruling.[6] Worth asked the Supreme Court
of the United States to review the case, but the Court declined,
denying certiorari in March 1988.[7]

IANAL, but this seems pretty conclusive to me...
Facts are not subject to copyright but compilations can be.  However,
the arrangement and presentation of the compilation has to be
sufficient to have merit protection.  For example, the SCOTUS denied
copywrite protection to phone books, which I think is entirely
relevant to this issue. (BUT INAL).
