You probably need to show example code, because I don't see this:
show search_path ;

I would rather not have to duplicate these across multiple schema - I'll
use plpgsql instead unless I've overlooked some other avenue.
I've found that I can create the function, in public, if I set the
search_path containing one schema (of course) and then successfully
access the function after resetting the search path to use a second
schema. My "build the world" scripting has so far avoided needing to
know/use any specific role. Another pipe dream vaporized?
Thanks,
