That would be a nice, but naïve, approach. It is likely that (without
admitting any guilt by any party) postgresql already steps on some
patents. In fact, any project you can think of likely steps on some
patents. There are patents on network communication: the "getting a
message from a server to client" sort of thing.

If you spent the next twenty years searching through patents and
creating patches for postgresql to circumvent the patents, not only
would you turn postgresql into a shriveled raisin of its current
self, you would be exposing postgresql to greater damages than if you
had never looked at the patents.

***Please- for the safety of everyone on these lists- do not mention
or link to any specific patents. This mailing list has a publicly-
accessible archive which could be used against me or you (at least in
the USA).***
