 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.

 agent stops working completely. So nothing can be installed or uninstalled
 anymore.

 again.

 uninstallation script part for this postgis bundle, and I'm good.

 Working on the scripts now.  Will try to do.  If you have something
 already prepared, feel free to attach a patch for it.
