Per-database does sound easier than per-table. I'd have to think about
how that would affect shared catalogs though.

For now, I'm leaning toward an offline utility to turn checksums on or
off, called pg_checksums. It could do so lazily (just flip a switch to
"enabling" in pg_control), or it could do so eagerly and turn it into a
fully-protected instance.

For the first patch, it might just be an initdb-time option for
simplicity.
