/**
 * An ent may represent not necessarily a node in the graph, but also an edge
 * between two nodes. Consider EntMember in the below example:
 *
 * vc.principal <--- EntMember[user_id, company_id] ---> EntCompany
 *
 * This predicate verifies that for a e.g. given EntCompany row and a given VC,
 * an EntMember row exists (and optionally matches some criterion) in the
 * database.
 *
 * - entEdgeVCField = user_id in the above example
 * - entEdgeFKField = company_id in the above example
 * - if an EntMember object exists, it must also match entEdgeFilter()
