Change the bootstrap sequence so that toast tables for system catalogs are created in the bootstrap phase proper, rather than added after-the-fact by initdb. This is cleaner than before because it allows us to retire the undocumented ALTER TABLE ... CREATE TOAST TABLE command, but the real reason I'm doing it is so that toast tables of shared catalogs will now have predetermined OIDs. This will allow a reasonably clean solution to the problem of locking tables before we load their relcache entries, to appear in a forthcoming patch.

Make it possibly to specify GUC params per user and per database. Create a new catalog pg_db_role_setting where they are now stored, and better encapsulate the code that deals with settings into its realm. The old datconfig and rolconfig columns are removed. psql has gained a \drds command to display the settings. Backwards compatibility warning: while the backwards-compatible system views still have the config columns, they no longer completely represent the configuration for a user or database. Catalog version bumped.

Revisit AlterTableCreateToastTable's API once again, hoping to make it what pg_migrator actually needs and not just a partial solution. We have to be able to specify the OID that the new toast table should be created with.
