How long is a long time?

A dump query, sorry.

Can you give as the output from 'EXPLAIN ANALYSE', so we can see not
only the estimate cost? How long is the real result? Perhaps, you have
wrong statistics, perhaps. And: without any WHERE - Conditions, every
SELECT-Query ends in a 'Seq Scan', and this will be slow. What do you
expected?
