what makes you spend so much time with pg-related utitilies?

Oh wow! Do you just use it to track content personally, or is it for an app?

I have a 2TB PostgreSQL database with 3 billion rows used to track content; I use periods so that I can UPDATE without losing old data, and I use ephemeralpg for unit tests and ad-hoc experimentation to avoid risking a production server. I have no real alternatives to PostgreSQL so I am glad that it is pretty adequate.
