Hi

I hope this is the right list to write to.

A danish company just got a patent which we at SSLUG www.sslug.dk do not
think is a new invention.

I want to get in contact with somebody who can confirm that this patent is
not new and has been in PostgreSQL before the patent was taken.

If we can prove that this patent was not new when requested, we plan to
start a trial against the company or Patent Office to get the patent
redrawn.

It is a bit troublesome to get all the documents. 
You can find a tar-ball here:

There is four pages which is interesting:

I took only a brief look at them, so i may be in a state of
misunderstanding :)

As I understand it, the patent is about generating/composing queries
_before_ 
submitting them to backend, not about query processing in the backend.

So there is not much hope that postgres has done it before, as 99% of
postgres 
is concerned with backend activities.

Yes, it's a query generation technique separate from the database server,
generating and executing SQL queries on a set of tables in order to satisfy
some goal.

Has nothing to do with the RDBMS itself.
