<div align="left">Hallo</div>
<div align="left"> </div>
<div align="left">I think it couldn't be held high enough in this comparasion that postgis is an open source project (and I guess that's what they want to hear at FOSS4G :-) ).</div>
<div align="left"> </div>
<div align="left">two examples</div>
<div align="left"> </div>
<div align="left">The 13 of aug Jose Carlos asked a question about strange performance when using indexes in a particular situation.</div>
<div align="left"><a href="http://postgis.refractions.net/pipermail/postgis-users/2009-August/024238.html">http://postgis.refractions.net/pipermail/postgis-users/2009-August/024238.html</a></div>
<div align="left"> After that we can all follow the discussions on the users and development lists and I realise myself that this is a problem I have had too without seeing it. Paul Ramsey and Tom Lane finds how to solve the problem in postgresql and 2009-09-09 the solution is released in postgresql 8.4.1. I think that is very impressive. A problem occurs in postgis and less than a month later the solution is released in postgresql. Even if the release of 8.4.1 wouldn't have been that close, Tom committed the solution about one week I think after Jose Carlos first message. So from that day it was possible for anyone to use it.</div>
<div align="left">I guess this was a special case, but worth mentioning.</div>
<div align="left"> </div>
<div align="left">the second example is about my own experiance with postgis.</div>
<div align="left">In january I asked about the same question on this list as Juergen Lorenz Simon did yesterday. </div>
<div align="left">the post from january:</div>

<div align="left"> </div>
<div align="left">I had about the same answer of solution then as Regina now suggests for postgis 1.4</div>
<div align="left"><a href="http://postgis.refractions.net/pipermail/postgis-users/2009-October/024838.html">http://postgis.refractions.net/pipermail/postgis-users/2009-October/024838.html</a></div>
<div align="left"> </div>
<div align="left">Since this is an open source project I downloaded the source and gave it a try. With some quite small modifications I could get the functionality I requested with great help and peptalk from the community (read Regina). And as the GPL license request I am happy to deliver it back as a suggestion for the future release.</div>
<div align="left">It was no big or advanced modification but it meant a lot to me, both for functionality and for the satisfaction of having managed it.</div>
<div align="left"> </div>
<div align="left">Thanks</div>
