Please remove the STRICT marking from the to_array(icollection, anyelement) function

[M-Butter]

Describe the problem

• What are you trying to solve?
  Without STRICT in the function definition of to_array(icollection, anyelement), I would be able to pass a null argument with the right type to obtain a correctly typed array from the icollection.
  Especially when a complex composite type is stored in the icollection, then that would save me the effort to construct a dummy instance of that complex composite type just to tell the to_array function what type I need.

Describe the proposal

• What is the feature you are proposing?
  Remove the STRICT marking from function to_array(icollection, anyelement) to allow the second argument to be a typed NULL value.

• How would it solve the problem?
  No (complex) constructor is needed for an element that is used just ot get the right type in the second argument.

Describe alternatives

• How would you solve the problem today if the feature is not built?
  Create an object with the right element type to pass as second argument for the to_array(icollection, anyelement) function.

• What other alternatives are there?
  There are several, but all to the cost of more code and less performance.
