The best way to do it is to have a layer between your application and
the database that can cache the results of your query. Unfortunately PHP
is not ideal for this - you might want to google for "php memcache" and
"pgmemcache" though.
Once you can cache the query, you run it once, use the row-count and
then fetch the rows from cache.
