Pavel Stehule:
2. But my main argument is, it is not really safe - it solves Peter's
use case, but if I use a reverse example of Peter's case, I still have a
problem.
I can have a variable x, and then I can write query like `SELECT x FROM x`;
but if somebody creates table x(x int), then the query `SELECT x FROM x`
will be correct, but it is surely something else. So the requirement of
the usage variable inside FROM clause doesn't help. It doesn't work.
But in this case you could make variables and tables share the same
namespace, i.e. forbid creating a variable with the same name as an
already existing table.
Best,
Wolfgang
