Before you get into that, try reducing these parameters:

work_mem = 1048576
They are way too high, especially the second one.
So if 1.5 MB maintenance_work_mem and 1 MB work_mem are "way too high",
why are the default values in the postgresql.conf on installation 16 MB
and 1 MB, respectively?
Replying to my own question - I must learn to check docs *before* asking:
<http://www.postgresql.org/docs/8.2/interactive/config-setting.html>
Some settings specify a memory or time value. Each of these has an
implicit unit, which is either kilobytes, blocks (typically eight
kilobytes), milliseconds, seconds, or minutes.
I was off by a factor of 1024 in how I read that. The OP had specified 1.5
*GB* and 1 *GB* respectively!
