Randomly Sort Rows in Postgres

I'm on a bit of a random kick lately. Today I learned you can randomly sort rows returned in a query using Postgres' random() function.

SELECT *
FROM users
ORDER BY random()

What it does is it calculates a random value for each row returned, and then orders by that calculated value. If the query returns a lot of rows this can be slow, so probably more useful for exploration or one-offs not necessarily for production uses.
