I was curious why pg did it that way. Here's a brief comment from him:

So similar to what Redis does today but a decade before Redis and likely faster than the databases of the day. Could have been important with loads of users editing their stores on slow hardware. Anyway it worked, they beat their 20 odd competitors and got rich. I'm sceptical that it was a poor design choice.
