Hi,

I can't find any legal way of calling this function.
SELECT bar(f) FROM foo f;
ERROR: set-valued function called in context that cannot accept a set
SELECT * FROM foo f, bar(f);
ERROR: function expression in FROM may not refer to other relations
of same query level
Any help appreciated.
You need LATERAL support for this:
SELECT * FROM foo f LATERAL bar(f);
I'm not sure about the syntax, but LATERAL is a standard JOIN type
wherein upper "nodes" are visible.
