This will make Postgres' optimizer use an index scan. Not to mention the fact that LIMIT without an ORDER will return you some random rows from a table... besides, if you are running Postgres with default options, you should increase the amount of memory it allocates for buffers and sorting. By default Postgres is VERY conservative about memory usage. -- Yours, Alexey V. Borzov, Webmaster of RDW
