This adds the types
anyelementandanynonarray, in addition to adding support for defining functions that use polymorphic types.https://www.postgresql.org/docs/15/extend-type-system.html#EXTEND-TYPES-POLYMORPHIC
Besides the changes to function resolution, this also adds a new parameter so that functions can see which types are passed in. This also cleans up the function interface, so that function definitions are a little more consistent and slightly less prone to typos (such as changing function parameters to an array from a slice, so that the length must be defined).
