For a beginner, a "relation 'foo' does not exist" is a clean message,
but a "function foo() does not exist" from an example in the doc are a real
problem. And, in this example in my first post, the call to the
nonexistent function are neither necessary nor 'to-the-point' to explain a
for-loop.
The starting point for my post was a real question on IRC today.
Someone was really confused because he tried to use this nonexistent
funktion to log something into a log-file. I think, this example can
rewritten, either without this funktion-call or with raise notice ...
Regards, Andreas
