1. getBackendSpecificForeignKeyName :: BackendSpecificOverrides -> Maybe (EntityNameDB -> FieldNameDB -> ConstraintNameDB)

   esqueleto	Database.Esqueleto.Experimental

   If the override is defined, then this returns a function that accepts an entity name and field name and provides the ConstraintNameDB for the foreign key constraint. An abstract accessor for the BackendSpecificOverrides

2. getEntityForeignDefs :: EntityDef -> [ForeignDef]

   esqueleto	Database.Esqueleto.Experimental

   No documentation available.

3. setBackendSpecificForeignKeyName :: (EntityNameDB -> FieldNameDB -> ConstraintNameDB) -> BackendSpecificOverrides -> BackendSpecificOverrides

   esqueleto	Database.Esqueleto.Experimental

   Set the backend's foreign key generation function to this value.

4. subSelectForeign :: (BackendCompatible SqlBackend (PersistEntityBackend val1), PersistEntity val1, PersistEntity val2, PersistField a) => SqlExpr (Entity val2) -> EntityField val2 (Key val1) -> (SqlExpr (Entity val1) -> SqlExpr (Value a)) -> SqlExpr (Value a)

   esqueleto	Database.Esqueleto.Experimental

   Performs a sub-select using the given foreign key on the entity. This is useful to extract values that are known to be present by the database schema. As an example, consider the following persistent definition:

   User
   profile ProfileId
   
   Profile
   name    Text
   

   The following query will return the name of the user.

   getUserWithName =
   select $
   from $ user ->
   pure (user, subSelectForeign user UserProfile (^. ProfileName)

10. newIdentFor :: DBName -> SqlQuery Ident

    esqueleto	Database.Esqueleto.Internal.Internal

    Create a fresh Ident. If possible, use the given DBName.
