Im using a statistical program that runs on PostgreSQL v9.3 and it allows user to create statistics as we see fit, right now im creating some statistics that it columns arent cachable and its due to the fact subqueries arent cachable so i need them to be added or take it into account by the software cache to improve their performance...thoughts?

PS: Even tho i know my way around the statistical program i have to say im a PostgreSQL noob.
