Without diving into all the detailed nuances of this discussion, this 
particular paragraph made me wonder if at least part of the problem here 
is that the same search_path is used to find "things that I want to 
execute" (functions and operators) and "things I want to access" 
(tables, etc).

I think many folks would be well served by only having system schemas in 
the search_path for the former (augmented by explicit schema qualifying 
of one's own functions), but agree that almost no one wants that for the 
latter (needing to schema qualify every table reference).

Should there be a way to have a separate "execution" search_path?
