Data layer functions

Allow DataLayer Filters (like, ilike from postgres in filter)

depends on

• Feat/mark i like functions as predicates ash_postgres#205
• feat: support functions in parse predicates ash#874

Very naive first implementation. It works in my project already, but I feel I'm probably missing some edge cases.
Somehow, the filter is already only applied to String attributes, but I'm not completely sure why.

AshGraphql is looking for functions that are type-compatible. In ilike and like it has a type signature f [[:string, :string]]

(Thats why it knows what types to support)

[zachdaniel]

Okay, maybe not 😆 I’m not sure how it could only be supporting strings. I think the function variation will need to do something similar to what the operator code does. In fact, ideally they’d share the same code instead of branching.

I may have looked at the wrong place.

Is this good to go?
