I don't know if you could drop/rebuild an index on a system
catalog while the database is online.
But there was sometimes a utility called reindexdb. That used
the bootstrap processing mode interface of the backend to
drop and recreate all system catalog indices. I don't know
who removed that and why, neither do I know if it would still
be possible to drop and reindex through the bootstrap
interface.
Does someone remember why it's gone?
