Usually because handshakes use a random salt on both sides. Not sure about pg's though, but in general collision strength is required but not slowness, they're not bruteforceable.
To be precise: collision resistance is usually not important for hashes used in authentication handshakes. Not for our MD5 authentication method anyway; otherwise we'd be screwed. What you need is resistance to pre-image attacks.
