Comment (by mdruve):

 Hey,

 when you are already working on the installer script, can I maybe add to
 please add the removal of the environment variables to the uninstaller
 part, too.

 Because when the postgis bundle gets uninstalled, the environment
 variables won't be removed. That's bad for the rest of the system,
 especially the CURL_CA_BUNDLE variable will point to a path which won't
 exist after the uninstallation and other programs will stop working
 completely because of the missing CA stuff.

 My used PC installer system OPSI is one of them, because their client
 agent stops working completely. So nothing can be installed or uninstalled
 anymore.
 I have to remove that environment variable by hand before it is working
 again.

 For now, I will add the removal of these variables in my own
 uninstallation script part for this postgis bundle, and I'm good.
 But it would be nice if this get fixed in the long run.

 Thanks in advance
