Hallo 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 :-)  ). two examples The 13 of aug Jose Carlos asked a question about strange performance when using indexes in a particular situation.http://postgis.refractions.net/pipermail/postgis-users/2009-August/024238.html 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.I!
  guess this was a special case, but worth mentioning. the second example is about my own experiance with postgis.In january I asked about the same question  on this list as Juergen Lorenz Simon did yesterday. the post from january:http://postgis.refractions.net/pipermail/postgis-users/2009-February/022699.html I had about the same answer of solution then as Regina now suggests for postgis 1.4http://postgis.refractions.net/pipermail/postgis-users/2009-October/024838.html 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.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. ThanksNicklas

>Title: PostGIS and Oracle Spatial
>Oracle Spatial and PostGIS are two of the most mature implementations of a spatial type system for their relevant host databases.
>With Postgres increasing in strength, and offshoot EnterpriseDB aiming to convert businesses running Oracle to EnterpriseDB/Postgres, the question of the relative merits of each of the spatial implementations arises.
>This talk will attempt to provide the audience with an understanding of the relative strengths and weaknesses of the two implementations so that they can feel they have some useful information which might aid decision making for new installations or conversions.
>While I already have quite a bit of material I thought I would ask the PostGIS community for suggestions as to what they would like covered if they were attending FOSS4G. Nothing worse than attending a presentation and, at the end, saying to youself that it was not what you expected and that nothing much was of use.
