Yes. Make sure you have a good column to partition on. Tables this large
are just bad performers in general, and heaven forbid you ever have to
perform maintenance on them. We had a table that size, and simply
creating an index could take upwards of two hours.
If you can't archive any of the table contents, partitioning may be your
only solution. If you have an EDB 9.1, you'll also have less problems
with the legacy issues people had with planning queries using partitions.
Don't go crazy, though. I try to keep it under a couple dozen partitions
per table, or under 100M records per partition.
