with PostGraphile you pretty much are in complete control. You're free to write your own postgres functions/views which postgraphile will expose as endpoints. you can do so such that they are standalone endpoints or sub-queries to the auto-generated table queries. you can also basically bypass all the auto-generated table queries by creating them in a schema that postgraphile doesn't introspect, and then write all the functionality you want in a schema that it will, thus getting only endpoints/queries that you wrote yourself exposed in the api.
