satisfactory.We could turn it on permanently, but that would break a lot of legacy code. What we really need is a way
ofmarking a function with some attributes. Of course, we could put it in the program text like plpgsql's
#variable_conflict,but that's really rather ugly. The grammar already has an attribute mechanism for functions, and
ISTMwe just need to extend that a bit to allow setting of function attributes reasonably flexibly, much as we can now
specifyformat options on EXPLAIN or we'll soon be able to specify options for foreign table
What does the existing attribute grammar for functions look like? An example perhaps?
Best,
