If a database object is to be accessed unqualified by all users, isn't the 'public' schema a perfect fit for it? How will it be helpful to create different database objects in different schemas, if also adding all such schemas to the search_path so they can be accessed unqualified? In such a scenario you risk unintentionally creating conflicting objects, and whatever schema happened to be first in the search_path will be resolved. Seems insecure and messy to me.
Heh. This is actually exactly what I wanted to do.
The use case is: version upgrades. I want to be able to have a search_path of something like 'pg_catalog, compat, public'. That way we can provide compatibility versions of newer functions in the "compat" schema, which get taken over by pg_catalog when running on a newer version. That way all the compatibility crap is clearly separated from the stuff that should be in "public".
