Btw, the default setting does already work like this: "$user",public.
It is not an error for "$user" not to exist, but it is a very nice
default because it will be used as soon as it appears.
It would be logical to treat all other cases the same. I then could
put the search_path into my .psqlrc and then have a "one size fits
all" search path for all my databases, etc...

As it looks impossible to divide the gray area, I'd opt to just drop
the warning and accept all syntactically valid strings.
