pg_dump not dumping default_text_search_config WAI?

I just got bitten by dumping and restoring a database to a new cluster, and the default_text_search_config was not copied for the database.

A check of the dump file shows no 'ALTER DATABASE' command.

I used an 'ALTER DATABASE...' to set it correctly and then did a dump, and the config was not in the dump.

From my understanding this is a cluster setting that only applies to this database, and ISTM that database config *should* be in the dump.

Is this WAI? Are there other database settings that are not exported by a pg_dump?
