PostgreSQL packaging on Mac OS X is a mess

It appears to me - based primarily on what I see on Stack Overflow rather than direct Mac use experience - that PostgreSQL packaging on Mac OS X is a real mess.

There are at least four widely-used competing package systems:

Fink and MacPorts packages also exist, but seem to have either fallen into disuse or "just work" so I don't see breakage reports about them.

If you haven't yet read the DataGenetics post on PIN frequency, you should. It's an amazing article with some extremely impressive data visualisation.

If you see your bank/ATM PIN in the frequency tables there, smack yourself for being predictable, then go have a chat with a random number generator.

I was unsurprised but relieved to see that I'm unpredictable, but not suspiciously and unusually unpredictable. Just where you want to be.

BTW, if you're a software developer who has anything even tangentially to do with security and you don't know what "hash" and "salt" mean or the difference between hashing and encryption, consider yourself dead-fish-slapped. Go. Learn. Now, before you contribute to this dataset.
