For scalability the new tablespaces are a major improvement, in that they
allow enhanced allocation of portions of the database to different disks.
This can massively improve speed in RAID environments, or even just
multi-disk environments. PITR isn't a big deal for me, but might be for
you.

I like programming in perl and the new pl/perl adds a totally new
dimension to databasing. For example, the dbi-link
(http://pgfoundry.org/projects/dbi-link/) project allows you to create
a schema within your database that mirrors another data source (any
data sources available via perl DBI). You could have an XML file
served from the web as a set of tables in one schema, a mysql database
as a second schema, and a set of csv files in a directory as a third
schema, all with views within Postgres that allow query, update,
delete, etc. Other projects such as this are likely to spring up, I
would imagine. Performance characteristics aside (which I will leave
to others to comment about), I have found the pl/perl improvements well
worth the switch.
