out of memory for query, partitioning & vacuuming

Hi -
I'm not a particularly experienced dba, so I'm hoping this isn't a
ridiculous question.
I have a 5 GB table with lots of churn in a 14 GB database. Querying
this one table without limits has just started throwing "out of memory
for query" from multiple clients (psql, java). I'm working with the
developers to look at it from the client side, but I'm wondering if
either partitioning the table or more aggressive vacuuming of this table
would have an effect on the out of memory problem.
I'm running 8.3.5 on solaris 10.
Thanks!
Mija
