Log message:
	Teach planner to expand sufficiently simple SQL-language functions
	('SELECT expression') inline, like macros, during the constant-folding
	phase of planning.  The actual expansion is not difficult, but checking
	that we're not changing the semantics of the call turns out to be more
	subtle than one might think; in particular must pay attention to
	permissions issues, strictness, and volatility.
