That's very very old. Everyone has contributed under the understanding the product is GPL, a license change is very unlikely. The only change that occurred was the Java client code under ./java got moved to an LGPL license, so people could use it in their software directly and not have a GPL issue. If all that is happening is your application is *using* PostGIS, as a database extension, in an unmodified-as-downloaded state then there is no GPL issue at all. If you happen to have modified *PostGIS itself*, then do return or publish those changes.
This isn't a FAQ, but it seems to take too many words to resolve :/ P On Thu, Sep 24, 2009 at 10:29 PM, Madhav Vodnala <[email protected]> wrote: > This link has some old discussion on this subject. > http://postgis.refractions.net/pipermail/postgis-users/2001-August/000207.ht > ml > > Not sure what is the current status. > > Perhaps it's good idea to post a short notes on licensing at > http://postgis.refractions.net > > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Paul > Ramsey > Sent: Wednesday, September 23, 2009 8:02 AM > To: PostGIS Users Discussion > Subject: Re: [postgis-users] Postgis-CommercialLicence > > There is no implication with using the database, you can license your > client software anyway you like. > > On Wed, Sep 23, 2009 at 5:30 AM, iceDice <[email protected]> wrote: >> >> Hello, >> >> I want to develop commercial Java GIS application and use PostgreSQL with >> Postgis for storing spatial data.
