The in-memory representation of the Catalog. This struct is not directly used to persist metadata to persistent storage. For persistent metadata see mz_catalog::durable::DurableCatalogState.

Serialize is implemented to create human readable dumps of the in-memory state, not for storing the contents of this struct on disk.

Update in-memory catalog state from a list of updates made to the durable catalog state.

Returns builtin table updates corresponding to the changes to catalog state.

Install builtin views to the catalog. This is its own function so that views can be optimized in parallel.

The implementation is similar to apply_updates_for_bootstrap and determines dependency problems by sniffing out specific errors and then retrying once those dependencies are complete. This doesn’t work for everything (casts, function implementations) so we also need to have a bucket for everything at the end. Additionally, because this executes in parellel, we must maintain a completed set otherwise races could result in orphaned views languishing in awaiting with nothing retriggering the attempt.
