a lot of familiarity with how the data is stored

Which is EXPLICITLY FORBIDDEN by the relational definition!

Exactly my point about Postgres taking a lot of ideas from the NoSQL crowd.

In Pick, I know *exactly* how my data is stored, because I told the database how to do it. Which is why Pick databases can be a mess because it's not properly normalised :-( The programmer needs to normalise his FILEs properly or you can lose the benefits. I've seen too many badly normalised FILEs that are a pain to work around.
