Обсуждение: pgsql: Ensure generic plan gets used for a plpgsql expression with no p

Ensure generic plan gets used for a plpgsql expression with no parameters.

Now that a NULL ParamListInfo pointer causes significantly different
behavior in plancache.c, be sure to pass it that way when the expression
is known not to reference any plpgsql variables.  Saves a few setup
cycles anyway.
