Given the real file growth problems we have analyzed over the past
month, I think we need to rethink the tools we give to users.

First, I think we need a section in the admin/maintenance manual talking
about reindex. (We already have vacuum there, and I think reindex is
something that periodically also should be done.)

Second, reindex on an entire database only works for stand-alone
databases. Now, I know we can't reindex system tables on a live
database, but should we enable REINDEX all non-system tables for a
database, similar to how we use vacuum? Do we need the reindex script
like vacuumdb?
