PokerTracker

I am using a 3rd party application to connect to my postgreSQL database.

first question is, when i create a custom stat, Is this stat stored only in poker tracker 3 or can i also browse info about my custom stat in postgreSQL'ls aminIII?

Second question i guess is more geared towards a PostgreSQL only forum.... so i'll hold off on that for now.

The information on the stat is stored in PT3 itself but we do generate a cached column which stores the aggregated results on a per-player basis (actually it's broken down a little further into number of players, limit and a couple of other things - but you should be able to easily deduce all you need from the way the cache table is built).
