pg_dump files with the custom format can be used to selectively restore
tables. It's really easy and a lot more reliable than filesystem level
backups - which require snapshotting or shutting down the database or
in-database support to get clean backups of.

If you consistently have hardware problems that cause filesystem corruption,
you should probably consider fixing that before worrying too much about
which software is on top of it being corrupted.

And, honestly, if keeping all the files in once place is a major problem for
you, then don't use PostgreSQL. It's not like it's going to be changed in
this regard.
