Can you install PostGIS on a different schema?
Most people have their default schema set to public so not explicitly specifying an install schema will generally install postgis in the public schema. Now I’ll create a new schema to move it and add this schema to search_path
Why is the next version of PostGIS needed?
The next version step is needed in order to upgrade all the schema qualified function references to the new schema location. next is designed to allow upgrading a postgis extension to a version it is already on. Trying to run UPDATE TO “2.4.1” when you are already on 2.4.1 would trigger an error that you are already on that version.
How to check PostGIS extension in arc catalog?
Arc Catalog somehow, after not finding a PostGIS extension, created it without notifying the User. To check that, you could look at the existing tables before and after that step. If you see this, PostGIS has been installed as an extension. The third possibility would be that ArcCatalog does something like this:
How to add functions to a custom schema?

How to set the search path in PostGIS?
You can set the search_path at run time using the SET command: SET search_path = census, public; This ensures that all references to relations and functions are searched in both the census and the public schemas. Remember that all the PostGIS functions and types are in public so we don’t want to drop that from the search path.
