What are effective_cache_size and work_mem set to? The defaults? They are good candidates to be increased. effective_cache_size could be set to (for example) 10GB, depending on how much memory gets consumed by the other application(s) running on that server.
The EXPLAIN ANALYZE plan of your query will show if work_mem needs to be increased, as there will be a line saying something like "External merge: disk sort" (or something like that, can't recall the exact message off the top of my head).
In development computer from where explain was posted and problem with copy of database also occurs:"shared_buffers";"128MB";"configuration file"
You likely want to bump that up closer to 1GB.

In devel computer where tests are performed, 4 GBReal server has 16 GB RAMReal server is for Postgres for this database and ASP.NET MVC3 application which uses this same database from postgres.
