We are planning on deploying postgres 8.4 in a month or two to
production. From the expected feature list for 8.5, I have seen one on
simplified table partitioning.
Will 8.5 have table partitions as first-class objects (i.e not
inheritted tables..but partitions)
Also..will 8.5 have a migration option to future releases without
dump/restore (e.g 8.5 to 9 )
If so, we may consider waiting.
Thank you
Sriram

It is already 9.0.

No. That patch was not added to 9.0:

There is no such built-in functionality. However, probably pg_migrator
will be available for 9.0, too.
To sum up: 9.0 has big features, like replication, etc. IMHO it won't be
production ready for a few months after it is released (yeah, I'm a bit
optimistic here). So you should stick to 8.4 for now.

What was originally going to be 8.5 was renumbered to be 9.0. None of
the planned partitioning improvements are included in it. The changes
planned there aren't a large as you seem to think they are though.
Partitions will still be inherited tables, the improvements are just
going to reduce the amount of setup/trigger code you need to write and
make management tasks easier.
