Re: Plpgsql function with unknown number of args

You don't have to cast it as anything, just return a refcursor from your
function.

Say you return a refcursor called return_cursor

select myfunction(your_in_array);
fetch all from return_cursor;

If you are calling from a development environment, you put the return
value of the fuction (the refcursor name) into a variable, then
dynamicly build the fetch
all statement from return value of the function. This must be done in
the context of a transaction, i.e. both statements must must be executed
in the same transaction.

The refcursors work really well and are very flexible.
