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
