2017-05-11Fixed #28107 -- Disabled grouping of selected primary keys for unmanaged models.Simon Charette
The grouping caused an issue with database views as PostgreSQL's query planer isn't smart enough to introspect primary keys through views.

2017-05-01Refs #16187 -- Stopped compiling query compilers during lookup rhs processing.Simon Charette
Lookup right hand side processing was compiling query compilers which happened to work by chance as SQLCompiler defines a as_sql() method with two optional parameters albeit it doesn't expect the same type of arguments.
