I added the Cast here, as postgres complained about a mismatch in type.

I approve of @ozer550's changes!
As for my changes, I resolved merge conflicts, fixed a postgres error, ensured our buffered chunks are always partitioned by model, and did some refactoring for partitioned buffers and self-ref FK lookups.

No concerns from a read through, and the implementation matches the spec to my eyes. No obvious artifacts from the merge conflict resolution.

Summary
Introduce deterministic ordering support for self-referential foreign key (FK) models during sync by adding a _self_ref_order field to Morango store records, allowing store/buffer rows to be processed parent-before-child in a streaming-friendly way. Adds a morango_ordering hook for syncable models so Morango can order querysets consistently (with nulls last), and adds a SELF_REF_ORDER capability to negotiate support between peers and preserve backwards compatibility.
