Yes, it's an established practice. I'd call it something just short of
a best practice though, as it really depends on your situation. I'd
take those articles with a grain of salt, as they are very
Oracle-specific (e.g. we do not have fat indexes (yet!), nor segments).
I also find his examples a bit contrived, and the whole "multi-user"
argument irrelevant for common cases. I lean towards using separate
tablespaces in Postgres, as the performance outweighs the additional
complexity. It's down on the tuning list however: much more important
is getting your kernel/volumes configured correctly, allocating
shared_buffers sanely, separating pg_xlog, etc.
