We have several TB database in production and it works well on
HP rx1620 dual Itanium2, MSA 20, running Linux. It's read-only storage for
astronomical catalogs with about 4-billions objects. We have custom
index for spherical coordinates which provide great performance.

Hi all,
I have a user who is looking to store 500+ GB of data in a database
(and when all the indexes and metadata are factored in, it's going to
be more like 3-4 TB). He is wondering how well PostgreSQL scales with
TB-sized databases and what can be done to help optimize them (mostly
hardware and config parameters, maybe a little advocacy). I can't
speak on that since I don't have any DBs approaching that size.
The other part of this puzzle is that he's torn between MS SQL Server
(running on Windows and unsupported by us) and PostgreSQL (running on
Linux...which we would fully support). If any of you have ideas of how
well PostgreSQL compares to SQL Server, especially in TB-sized
databases, that would be much appreciated.
We're running PG 8.2.5, by the way.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
