The best part is that you can skip the LIMIT/OFFSET entirely if you put page numbers in your cache table while inserting into it, via a temporary sequence or something. Retrieving the results will then be very fast, but beware that SELECT * FROM table WHERE id =ANY( array ) won't use an index, so

contrib/intarray provides index access to such queries.

Can you provide an example of such a query ? I've looked at the operators for intarray without finding it.

for example, http://www.sai.msu.su/~megera/postgres/gist/code/7.3/README.intarray

SELECT * FROM table WHERE id && int[]
