GRDB.swift: Expression tree is too large (maximum depth 1000) with `including(all:)`

What did you do?

• When loading 1000+ objects from a series of joined tables via RxGRDB observeAll we are seeing SQL errors and a failure to produce the objects:

Expression tree is too large (maximum depth 1000) in "SELECT *, "id" AS "grdb_id", "opco" AS "grdb_opco" FROM "productPricingAppliedDiscount" WHERE ("customerId" = ?) AND ("opco" = ?) AND ((("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?)) OR (("id" = ?) AND ("opco" = ?))...

What did you expect to happen?

• The objects to be returned

What happened instead?

• SQL errors and no objects are pulled from the tables
