I agree with all of the follow ups that having indexes on every
column is a bad idea. I would remove the indexes from the
least searched upon 10-20 columns, as I'm sure this will help
your performance.
You mention that not having indexes on some of the columns because it
"may slow down user queries". I think you should investigate this and
make sure they are necessary. I've seen many an application, with far
more rows than you're dealing with, only need 1 or 2 indexes, even
when all (or most) columns could be searched.
Also, you should consider increasing your shared_buffers and probably
your sort memory a touch as well. This will help your overall
performance.
