Pavel Stehule:
When you write RAISE NOTICE '%', x, then PLpgSQL parser rewrite it to
RAISE NOTICE '%', SELECT $1
There is no parser just for expressions.
That's why my suggestion in [1] already made a difference between:
SELECT var;
and
SELECT col, var FROM table, var;
So the "only require variable-in-FROM if FROM is used" should extend to
the SQL level.
That should be possible, right?
Best,
Wolfgang
