Thanks for the clarification, Dave. I posted the question here because this was the only place I could find where there already seemed to be a relevant discussion, but now I know about the EDB forum that's obviously a much better place.
In terms of the problem, I downloaded the EDB AS 8.3 installer (not MSI - you're right of course) from your website yesterday and went through the installation process several times, trying various combinations of options or accepting all the default options. PostGIS simply did not install and I couldn't even find it in the folders. Obviously there's something fishy going on there, but maybe it's something to do with my setup, although given the simplicity of the installer it would seem that there are only a limited number of places where I could screw it up! In the meantime, I've gone back to EDB AS 8.2, which clearly gives you the option of installing PostGIS during the installation process. Works for me, anyway. To be honest, I think the idea of having the option to install various components, including PostGIS, as in 8.2, makes for a better and more flexible installer. You can still go for the defaults if required, but at least you have a little more room to tailor your installation and investigate any problems. Maybe your other users might appreciate this flexibility? Thanks again for your help. -- View this message in context: http://www.nabble.com/BUG--3953%3A-No-PostGIS-option-in-installer-tp15428856p16656751.html Sent from the PostgreSQL - bugs mailing list archive at Nabble.com. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
