How to keep track of all the trademarks? I'll try the strategy used at
www.qnx.com - thomas
+--
+
+--
+There is no legal requirement to make trademark acknowledgements in
+references to third party products that happen to have trademarked
+names.
+
+The exception would be if PostgreSQL were to license a particular
+trademark and the trademark holder makes this requirement (as in the
+case of UNIX and Java).
+
+What is not allowed, however, is to use a trademark name in a way that
+could lead people to believe that they label PostgreSQL products.
+E.g., "the PostgreSQL UNIX database system" would probably be illegal,
+whereas "PostgreSQL, which runs on many UNIX computer systems" is
+fine. This is independent of whether a trademark acknowledgement is
+made.
