It probably won't solve this problem, but you need to upgrade. The
latest 8.3 release is 8.3.7. See
http://www.postgresql.org/support/versioning

You'll have to give more details or no-one will be able to help you.
Please share the query that caused the crash, and CREATE statements of
all the tables involved in the query. Is there any triggers or anything
else involved?

Can you get a core dump and post stack trace from it? Something along
the lines of:
1. ulimit -c unlimited
2. pg_ctl start
3. <induce crash>
4. gdb /usr/bin/postgres <datadir>/core
5. bt
