- * The first time any Oper or Func node is evaluated, we compute a cache
- * record for the function being invoked, and save a pointer to the cache
- * record in the Oper or Func node.  This saves repeated lookup of info
- * about the function.

- * A FunctionCache record is built for all functions regardless of language.

- * We store the fmgr lookup info to avoid recomputing it on each call.
- *
- * We also need to store argument values across calls when evaluating a
- * function-returning-set.	This is pretty ugly (and not re-entrant);
- * current-evaluation info should be somewhere in the econtext, not in
- * the querytree.  As it stands, a function-returning-set can't safely be
- * recursive, at least not if it's in plpgsql which will try to re-use
- * the querytree at multiple execution nesting levels.	FIXME someday.
