Well, not as misleading as nonspecific. I did incorrectly assume
the OP was referring to store types. Still, there's no "plug-in"
solution in either case. Sorry for the misdirection.

This is misleading.
Core Data does not support adding new store types in that the
underlying store API is not available.
However, Core Data is still quite useful when integrating with
various databases and network based data sources. The
NSManagedObjectContext and the rest of the object graph management
mechanisms provide all the hooks necessary to identify all state
changes of the object graph in a succinct and timely fashion.
These hooks can -- and often are -- used to update some remote data
source as managed objects are changed in an, often, in-memory store.
Certainly, not as elegant as it would be if Core Data supported
said database [Postgres, in this case], directly. But it does
enable you to take full advantage of Core Data's validation, object
graph management, undo/redo and other features, all of which can
still save a huge amount of development time.
