Really slow query on 6.4.2

Not sure if I should post this here, but it seemed kinda appropriate.
Anyway, I'm using 6.4.2 and execute the following query in psql, piping the
results to a file:
"select autos.*, owners.name, owners.email, owners.dphone, owners.ephone,
owners.zip, owners.country from autos, owners where autos.ownerid =
owners.id;"
This takes about 60 seconds at 0% idle CPU, with the backend taking all the
time. The file ends up about 3MB. Both tables have between 1200 and 1600
rows with about 25 and 7 columns respectively.
A simpler query like:
"select * from autos;" takes about a second at about 50% idle, and produces
a similiar amount of data in a 3MB file.
Any hints on speeding this up?
OS: Redhat Linux 5.1, Dual-PPro 266.

The table definitions are below if anyone is interested:
(Also, the cdate default value doesn't get set properly to the current date.
Any hints on that would
be appreciated as well.)
Thanks,
Rich.
